2020-06-03GPUMaterial: Fix shader compilation when using UDIM texturesClément Foucault
2020-06-03GPUMaterial: Rework/simplify image texture filteringClément Foucault
This use the latest GPUTexture change to use the sampler state to avoid the pole issues instead of using GLSL hacks. This should fix T73942: Eevee mipmaps not respecting border mode. Note that this also fix some discrepencies between cycles and eevee (like boxmapping + clip).

This use the latest GPUTexture change to use the sampler state to avoid the pole issues instead of using GLSL hacks.
2020-06-03GPUMaterial: Add support for different sampler state per image samplerClément Foucault
This bridge between the new sampler state support from GPUTexture and draw material handling. The Sampler State is just the one from the texture for now. No change in logic.
2020-06-02EEVEE: Refactor of eevee_material.cClément Foucault
These are the modifications: -With DRW modification we reduce the number of passes we need to populate. -Rename passes for consistent naming. -Reduce complexity in code compilation -Cleanup how renderpass accumulation passes are setup, using pass instances. -Make sculpt mode compatible with shadows -Make hair passes compatible with SSS -Error shader and lookdev materials now use standalone materials. -Support default shader (world and material) using a default nodetree internally. -Change BLEND_CLIP to be emulated by gpu nodetree. Making less shader variations. -Use BLI_memblock for cache memory allocation. -Renderpasses are handled by switching a UBO ref bind. One major hack in this patch is the use of modified pointer as ghash keys. This rely on the assumption that the keys will never overlap because the number of options per key will never be bigger than the pointed struct. The use of one single nodetree to support default material is also a bit hacky since it won't support concurent usage of this nodetree. (see EEVEE_shader_default_surface_nodetree) Another change is that objects with shader errors now appear solid magenta instead of shaded magenta. This is only because of code reuse purpose but could be changed if really needed. Reviewed By: jbakker Differential Revision: https://developer.blender.org/D7642

2020-04-20Nodes: New Object and Image socket typesJacques Lucke
Those new socket types will be necessary for particle nodes. The main difficulty with adding these socket types is that they are the first that reference ID data in their `value`. Therefore, user counting code had to be added in a couple new places. Reviewers: brecht, mont29 Differential Revision: https://developer.blender.org/D7347
2020-04-20Simulations: Add simulation node tree typeJacques Lucke
This implements a new builtin node tree type called `SimulationNodeTree`. It is not yet embedded in the `Simulation` data block. The node tree will initially be used for the new particle nodes system. When the cmake option `WITH_NEW_SIMULATION_TYPE` is enabled, a new `Simulation Editor` is shown in the editors menu (which is just a node editor). This patch does not add entries to the Add Node menu, so it is empty. Reviewers: brecht Differential Revision: https://developer.blender.org/D7287

To make it clear that's not in the 0..1, but more of a terrain height value without a strict range.
2020-04-09Shading: add Roughness input to Noise and Wave texture nodesBartosz Moniewski
Currently in fractal_noise functions, each subsequent octave doubles the frequency and reduces the amplitude by half. This patch introduces Roughness input to Noise and Wave nodes. This multiplier determines how quickly the amplitudes of the subsequent octaves decrease. Value of 0.5 will be the default, generating identical noise we had before. Values above 0.5 will increase influence of each octave resulting in more "rough" noise, most interesting pattern changes happen there. Values below 0.5 will result in more "smooth" noise.

2020-03-11Eevee: internal support for arbitrary number of volume gridsBrecht Van Lommel
This has no user visible impact yet since smoke volumes only support a fixed set of attributes, but will become important with the new volume object. For GPU shader compilation, volume grids are now handled separately from image textures. They are somewhere between a vertex attribute and an image texture, basically an attribute that is stored as a texture. Differential Revision: https://developer.blender.org/D6952
2020-03-11Smoke: put density/color in separate textures, fixes for workbench shaderBrecht Van Lommel
This is more in line with standard grids and means we don't have to make many special exceptions in the upcoming change for arbitrary number of volume grids support in Eevee. The workbench shader was also changed to fix bugs where squared density was used, and the smoke color would affect the density so that black smoke would be invisible. This can change the look of smoke in workbench significantly. When using the color grid when smoke has a constant color, the color grid will no longer be premultiplied by the density. If the color is constant we want to be able not to store a grid at all. This breaks one test for Cycles and Eevee, but the setup in that test using a color without density does not make sense. It suffers from artifacts since the unpremultiplied color grid by itself will not have smooth boundaries. Differential Revision: https://developer.blender.org/D6951
2020-03-06Nodes: Support storing socket link limits in bNodeSocketTypeJacques Lucke
Currently the link limit of sockets is stored in bNodeSocket->limit. This allows for a lot of flexibility, but is also very redundant. In every case I've had to deal with so far, it would have "more correct" to set the link limit per socket type and not per socket. I did not enforce this constraint yet, because the link limit is exposed in the Python API, which I did not want to break here. In the future it might even make sense to only support only three kinds of link limits: a) no links, b) at most one link, c) an arbitrary number links links. The other link limits usually don't work well with tools (e.g. which link should be removed when a new one is connected?) and is not used in practice. However, that is for another day. Eventually, I would like to get rid of bNodeSocket->limit completely and replace it either with fixed link limits or a callback in bNodeSocketType. This patch consists of three parts: **1. Support defining link limit in socket type** This introduces a new `nodeSocketLinkLimit` function that serves as an indirection to hide where the link limit of a socket is defined. **2. Define link limits for builtin sockets on socket type** Data sockets: one input, many outputs Virtual sockets: one input, one output Undefined sockets: many inputs, many outputs (to avoid that links are removed when the type of the socket is not known) **3. Remove `bNodeSocketTemplate->limit`** This wasn't used anymore after the second commit. Removing it simplifies socket definitions in hundreds of places and removes a lot of redundancy.

2020-02-27Cleanup: more refactoring of GPU material attributes and texturesBrecht Van Lommel
This further separates requested attributes and textures from the actual node graph, that can be retained after the graph has been compiled and freed. It makes it easier to add volume grids as a native concept, which sits somewhere between an attribute and a texture. It also adds explicit link types for UDIM tile mapping, rather than relying on fairly hidden logic.

2020-02-21EEVEE: Render PassesJeroen Bakker
This patch adds new render passes to EEVEE. These passes include: * Emission * Diffuse Light * Diffuse Color * Glossy Light * Glossy Color * Environment * Volume Scattering * Volume Transmission * Bloom * Shadow With these passes it will be possible to use EEVEE effectively for compositing. During development we kept a close eye on how to get similar results compared to cycles render passes there are some differences that are related to how EEVEE works. For EEVEE we combined the passes to `Diffuse` and `Specular`. There are no transmittance or sss passes anymore. Cycles will be changed accordingly. Cycles volume transmittance is added to multiple surface col passes. For EEVEE we left the volume transmittance as a separate pass. Known Limitations * All materials that use alpha blending will not be rendered in the render passes. Other transparency modes are supported. * More GPU memory is required to store the render passes. When rendering a HD image with all render passes enabled at max extra 570MB GPU memory is required. Implementation Details An overview of render passes have been described in https://wiki.blender.org/wiki/Source/Render/EEVEE/RenderPasses Future Developments * In this implementation the materials are re-rendered for Diffuse/Glossy and Emission passes. We could use multi target rendering to improve the render speed. * Other passes can be added later * Don't render material based passes when only requesting AO or Shadow. * Add more passes to the system. These could include Cryptomatte, AOV's, Vector, ObjectID, MaterialID, UV. Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D6331
