2020-09-14Fix T80770: UV Image Editor: Display Texture Paint UVs Not WorkingJeroen Bakker
When developing the image draw engine I wasn't aware of this option. But now it is back.
2020-09-14DrawManager: Resolve Assert in Image EngineJeroen Bakker
Tiled texture uses different texture structure than normal textures. Normally we add dummy textures and use them, but I found it cleaner to have 2 shaders and use the correct shader.
2020-09-14DRW: Fix wrong use of GPU_blendClément Foucault
Use the enum instead of a boolean. Exibit n°5512 where typecast warning would have find the error.
2020-09-14Cleanup: DRWManager: Remove deprecated pass_state functionsClément Foucault
And also enable pass names when using `--debug-gpu` option.
2020-09-14Fix T80603 Workbench: Inverted alpha when renderingClément Foucault
This was caused by a left over DRWPass->state modification that made the subsequent samples redraw without Blending enabled. This led to incorrect blending. The fix is to use the new API for pass instancing.
2020-09-13Fix T80023 Invisible objects or glitches with object 'in front' + 'X-ray'Clément Foucault
Rendering only to the depth buffer seems to need a valid fragment shader with a color output on some platform.
2020-09-13CleanUp: Code foldingJeroen Bakker
Incorrect code folding in recent commit
2020-09-13Cleanup: spelling, update function name in commentsCampbell Barton
2020-09-12Fix remaining GL calls/type preventing from building due to recent cleanupClément Foucault
2020-09-12GPU: Fix wrong state before python callbacksClément Foucault
This was caused by a missing state apply. We force the GPUState to be set after the callbacks to avoid desync between our state tracker and the real gl state. This fixes some issues but a better general fix for all BGL would be better. This fix T80297 2.91 texture alpha is not transparent
2020-09-12Cleanup: Remove GLEW dependencies outside of GL moduleClément Foucault
2020-09-12GPU: Add Image Load Store extension supportClément Foucault
This wraps the functionality used to speedup EEVEE volumetrics. This touches the rendering code of EEVEE as it should fix a mis-usage of the GL barrier. The barrier changed type and location, removing an unused barrier.
2020-09-11GPUTexture: Return NULL texture if data grid is NULL tooSebastián Barschkis
In a recent update to the fluids modifier (rB03c2439d96e8), I introduced a flush call that sets all grids to NULL if the frame is outside of the allowed frame range. This way, the texture creation function must also check if the data grid is NULL before trying to create a texture. Reviewed By: fclem Differential Revision: https://developer.blender.org/D8872

2020-09-11Image Editor: Smooth Wire User PreferencesJeroen Bakker
The old image editor has an option to enable the smooth wire drawing. This option was stored per editor and disabled by default. This patch connects the smooth wires in the UV/Image editor to `User Prefereces -> Viewport -> Quality -> Smooth Wire [] Overlay`. The old option is left in place and will be removed when the old image editor drawing code will be removed before BCon 3.
2020-09-11Use DrawManager for Image/UV EditorJeroen Bakker
This project moves the current UV/Image editor drawing to the draw manager. Why would we do this: **Performance**: Current implementation would draw each texel per time. Multiple texels could be drawn per pixel what would overwrite the previous result. You can notice this when working with large textures. Repeat image drawing made this visible by drawing for a small period of time and stop drawing the rest. Now the rendering is fast and all repeated images are drawn. **Alpha drawing**: Current implementation would draw directly in display space. Giving incorrect results when displaying alpha transparent images. This addresses {T52680}, {T74709}, {T79518} The image editor now can show emission only colors. See {D8234} for examples. **Current Limitations** Using images that are larger than supported by your GPU are resized (eg larger than 16000x16000 are resized to 8k). This leaves some blurring artifacts. It is a low priority to add support back of displaying individual pixels of huge images. There is a design task {T80113} with more detail. **Implementation overview** Introduced an Image Engine in the draw module. this engine is responsible for drawing the texture in the main area of the UV/Image editor. The overlay engine has a edit_uv overlay which is responsible to draw the UV's, shadows and overlays specifically for the UV Image editor. The background + checker pattern is drawn by the overlay_background. The patch will allow us to share overlays between the 3d viewport and UV/Image editor more easily. In most cases we just need to switch the `pos` with the `u` attribute in the vertex shader. The project can be activated in the user preferences as experimental features. In a later commit this will be reversed. Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D8234
2020-09-10Fix T79737: ERROR ACCESS VIOLATION when switching to eevee rendered viewAristotelis Dossas
This prevents Blender from crashing when switching to rendered view and the grid_data is NULL in the lightcache (due to possible corruption), by switching to the fallback lightcache. The fix extends the solution for possible corruption in the cube_data as well. Fix T79737 Reviewed By: fclem Differential Revision: https://developer.blender.org/D8835

2020-09-09Fix T79038: Blender freezes on vertex paint on linked mesh dataJeroen Bakker
This change promotes the work-a-round to the current solution. There are options to solve this better, but needs more design.
2020-09-09Cleanup: Rename public "bUnit" functionsHans Goudey
This commit renames the functions in "BKE_unit.h` to be consistent with the naming in the rest of blenkernel. bUnit_AsString -> BKE_unit_value_as_string_adaptive bUnit_AsString2 -> BKE_unit_value_as_string bUnit_ReplaceString -> BKE_unit_replace_string bUnit_ApplyPreferredUnit -> BKE_unit_apply_preferred_unit bUnit_ToUnitAltName -> BKE_unit_name_to_alt bUnit_ClosestScalar -> BKE_unit_closest_scalar bUnit_BaseScalar -> BKE_unit_base_scalar bUnit_IsValid -> BKE_unit_is_valid bUnit_GetSystem -> BKE_unit_system_get bUnit_GetBaseUnit -> BKE_unit_base_get bUnit_GetBaseUnitOfType -> BKE_unit_base_of_type_get bUnit_GetName -> BKE_unit_name_get bUnit_GetNameDisplay -> BKE_unit_display_name_get bUnit_GetIdentifier -> BKE_unit_identifier_get bUnit_GetScaler -> BKE_unit_scalar_get bUnit_IsSuppressed -> BKE_unit_is_suppressed Differential Revision: https://developer.blender.org/D8828
2020-09-08GPU: Extract GPU Base Test caseJeroen Bakker
The draw manager test case initialized ghost, gpu and draw manager. This change splits the base test case to GPU specific and draw manager specific test case. The GPU test base test case will be used for low level GPU tests.
2020-09-08DrawManager: Fixed memory leak in test casesJeroen Bakker
Memory leak is introduced as test cases reinitializes the GPU stack. Added a call to GPU_backend_exit to fix this. In GPU_backend_exit the GPU backend was destroyed but the pointer wasn't reset for reuse. This patch also clears the pointer to be reused.
2020-09-08DrawManager: Move tests in namespaceJeroen Bakker
Using blender::draw::tests as namespaces.
2020-09-08Cleanup: DRW: Replace 0 by NULL in GPU_context_create callsClément Foucault
This was left from a previous refactor.
2020-09-08GPUImmediate: Make activation / deactivation implicitClément Foucault
This avoids unecessary complexity. Also makes the GPUImmediate threadsafe by using a threadlocal imm variable.
2020-09-08fix flushClément Foucault
2020-09-08GPUFramebuffer: Make GPU_framebuffer_read_depth more flexibleClément Foucault
This is to make use of it in selection code.
2020-09-07GPU: Rename gpu_extensions to gpu_capabilitiesClément Foucault
This makes more sense as this module has more to it than just GL extensions.
2020-09-07EEVEE: Try to allocate the lightcache and use fallback if failureClément Foucault
This is to remove an explicit opengl dependence to GPU_extension.
2020-09-07GPUExtensions: GL backend isolationClément Foucault
This is part of the Vulkan task T68990. This commits changes a few things: - Rename extensions to capabilities (but left the file name untouched). - Cubemap mip render workaround detection is rewritten using gl commands to avoid using the GPU API before initialization. - Put all the capabilities that are only relevant for the GL backend inside GLContext as static variables. - Cleanup the names of the limit variables. - Separate all GL related workaround search inside the GL module.

2020-09-06Cleanup: GPUVertBuf: Replace GPU_vertbuf_create by GPU_vertbuf_callocClément Foucault
This is a simple cleanup to make naming consistent with the rest of the module.
2020-09-06GPUVertBuf: Make GPUVertBuf private to the GPU moduleClément Foucault
This is just a cleanup to isolate the internals of the vertbuf. This adds some getters to avoid refactor of existing code.
2020-09-06GPUIndexBuf: GL backend IsolationClément Foucault
This is part of the Vulkan backend task T68990. There is no real change, only making some code re-organisation. This also make the IndexBuf completely abstract from outside the GPU module.

2020-09-05GPUTexture: Change texture creation APIClément Foucault
This is to modernize the API: - Add meaningful name to all textures (except DRW textures). - Remove unused err_out argument: only used for offscreen python. - Add mipmap count to creation functions for future changes. - Clarify the data usage in creation functions. This is a cleanup commit, there is no functional change. # Conflicts: # source/blender/gpu/GPU_texture.h
2020-09-05Cleanup: GPUTexture: Remove use of GPU_texture_create_nDClément Foucault
Use creation + update function instead.
2020-09-05GPUTexture: Implement back 3D texture resizeClément Foucault
But this time implement it outside the texture module. This makes more sense as only the volume textures need this feature.
2020-09-05Cleanup: EEVEE: Use correct array size and use equals_v2v2_intClément Foucault
2020-09-05GPUTexture: Remove bind to edit callsClément Foucault
This is going to be unecessary after the GPU opengl texture backend refactor. For now add a save/restore mechanism to leave the state untouched. Also remove some calls where the caller would bind to particular binding point and set the shader uniform.

The handling of missing volume grids for the principled volume shader was incomplete, different inputs need different default values.
2020-09-03Fix T63125: Gpencil: bones cannot be selected in weightpaint modePhilipp Oeser
Some underlying functionality was not ready for greasepencil: - BKE_modifiers_get_virtual_modifierlist (now introduce dedicated BKE_gpencil_modifiers_get_virtual_modifierlist) - BKE_modifiers_is_deformed_by_armature - checks in drawing code - checks in (pose) selection code A couple of changes to make this work: - `eGpencilModifierType_Armature` has to be respected (not only `eModifierType_Armature`) - `OB_MODE_WEIGHT_GPENCIL` has to be respected (not only `OB_MODE_WEIGHT_PAINT`) -- (now use new `OB_MODE_ALL_WEIGHT_PAINT`) - `gpencil_weightmode_toggle_exec` now shares functionality from `wpaint_mode_toggle_exec` -- moved to new `ED_object_posemode_set_for_weight_paint` This patch will also set the context member "weight_paint_object" for greasepencil (otherwise some appropriate pose operators wont work when in weightpaint mode) Reviewed By: campbellbarton Maniphest Tasks: T63125 Differential Revision: https://developer.blender.org/D8483
