2020-03-02Shading: Add invert option to Vector Rotate NodeCharlie Jolly
Checkbox to invert rotation angle, suggested by @simonthommes Differential Revision: https://developer.blender.org/D6932
2020-02-24Fix T74169: Vector Rotate Node - Euler modes not working as intendedCharlie Jolly
Remove additional Euler modes for the time being, not working as intended, will add back if there is a need.
2020-02-19Fix T73938: Cycles Vertex Color wrong if no layer is specifiedPhilipp Oeser
The node would render black in this case (but should use the 'active_render' layer choosen in the object data properties -- this is now in line to how this is handled for e.g. UVs) This introduces ATTR_STD_VERTEX_COLOR and uses this thoughout, if no particular layer is specified in the node.

This extends FindOpenShadingLanguage.cmake to also look for the location of stdosl.h and adds the path to the invocation of oslc to deal with the headers being in different locations a little better. Differential Revision: https://developer.blender.org/D6865 Reviewers: brecht
2020-02-17Cycles: Vector Rotate Node using Axis and Angle methodCharlie Jolly
This node provides the ability to rotate a vector around a `center` point using either `Axis Angle` , `Single Axis` or `Euler` methods. Reviewed By: #cycles, brecht Differential Revision: https://developer.blender.org/D3789
2020-02-17Shading: add direction modes and phase offset to wave texture nodeBartosz Moniewski
* Direction mode X, Y and Z to align with axes rather than diagonal or spherical as previously. X is the new default, existing files will use diagonal or spherical for compatibility. * Phase offset to offset the wave along its direction, for purposes like animation and distortion. https://developer.blender.org/D6382

2020-02-15Shading: Extend Vector Math Node with Sin, Cos, Tan and Wrap functionsCharlie Jolly
This adds some extra functions recently added to the float Maths Node. Not all functions have been ported over in this patch.

There were to copies of stdosl.h one from stock OSL and one in the cycles tree augmented with cycles specific closures. moved the cycles ones to stdcycles.h and copied the stock stdosl.h and accompanying headers from the OSL shader folder. for further details see D6812.

2020-02-04Fix wrong default value for Lacunarity in Musgrave textureBartosz Moniewski
Lacunarity parameter determines scaling of subsequent octaves in fractal noises. For example, Noise node have this scaling hardcoded to 2.0. Each octave have twice bigger scale than previous one, resulting in finer details. By design fractal noises that generate octaves with same seed should not have Lacunarity set to 1.0, since then it just stacks up identical noises.

2019-12-07Shaders: noise and wave distortion now work uniformly instead of diagonallyBartosz Moniewski
Previously Noise and Wave texture nodes would use noise functions within a [0,1] range for distortion effects. We either add or subtract noise from coordinates, never do both at same time. This led to the texture drastically shifting on the diagonal axis of a plane / cube. This behavior makes the Distortion input hard to control or animate. Capabilities of driving it with other texture are also limited, diagonal shifting is very apparent. This was fixed by offsetting the noise function to a signed range and making it zero-centered. This way noise is uniformly added and subtracted from coordinates. Texture pattern sticks to main coordinates which makes it way easier to control. This change is not strictly backwards compatible, there is versioning to ensure the scale of the distortion remains similar, but the particular pattern can be a little different. Differential Revision: https://developer.blender.org/D6177
2019-12-07Shader Nodes: Add Interpolation modes to Map Range nodeCharlie Jolly
Modes: Linear interpolation (default), stepped linear, smoothstep and smootherstep. This also includes an additional option for the **Clamp node** to switch between **Min Max** (default) and **Range** mode. This was needed to allow clamping when **To Max** is less than **To Min**. Reviewed By: JacquesLucke, brecht Differential Revision: https://developer.blender.org/D5827
2019-12-07Maths Node: Additional functionsCharlie Jolly
When creating shaders and using maths functions it is expected that Blender should match functions in other DCC applications, game engines and shading languages such as GLSL and OSL. This patch adds missing functions to the Blender maths node. Ideally, it would be nice to have these functions available to vectors too but that is not part of this patch. This patch adds the following functions trunc, snap, wrap, compare, pingpong, sign, radians, degrees, cosh, sinh, tanh, exp, smoothmin and inversesqrt. Sign function is based on GLSL and OSL functions and returns zero when x == 0. Differential Revision: https://developer.blender.org/D5957
2019-11-27Cycles: Add Random Per Island attribute.OmarSquircleArt
The Random Per Island attribute is a random float associated with each connected component (island) of the mesh. It is particularly useful when artists want to add variations to meshes composed of separate units. Like tree leaves created using particle systems, wood planks created using array modifiers, or abstract splines created using AN.

2019-09-12Shading: Add Vertex Color node.OmarSquircleArt

2019-09-12Shading: Add More Features To The Voronoi Node.OmarSquircleArt
This patch allows the Voronoi node to operate in 1D, 2D, and 4D space. It also adds a Randomness input to control the randomness of the texture. Additionally, it adds three new modes of operation: - Smooth F1: A smooth version of F1 Voronoi with no discontinuities. - Distance To Edge: Returns the distance to the edges of the cells. - N-Sphere Radius: Returns the radius of the n-sphere inscribed in the cells. In other words, it is half the distance between the closest feature point and the feature point closest to it. And it removes the following three modes of operation: - F3. - F4. - Cracks. The Distance metric is now called Euclidean, and it computes the actual euclidean distance as opposed to the old method of computing the squared euclidean distance. This breaks backward compatibility in many ways, including the base case. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5743
2019-09-09Shading: Extend Musgrave node to other dimensions.OmarSquircleArt

2019-09-05Shading: Rewrite Mapping node with dynamic inputs.OmarSquircleArt
This patch rewrites the Mapping node to support dynamic inputs. The Max and Min options have been removed. They can be added as Min and Max Vector Math nodes manually. Texture nodes still use the old matrix-based mapping. A new SVM node `NODE_TEXTURE_MAPPING` has been added to preserve this functionality. Similarly, in GLSL, a `mapping_mat4` function has been added. Reviewers: brecht, JacquesLucke
2019-09-04Shading: Extend Noise node to other dimenstions.OmarSquircleArt
This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D space. The noise code has also been refactored to be more readable. The Color output and distortion patterns changed, so this patch breaks backward compatibility. This is due to the fact that we now use random offsets as noise seeds, as opposed to swizzling and constants offsets.

2019-05-03Cleanup: refactor Cycles OSL texture handlingBrecht Van Lommel
This adds our own OSL texture handle, that has info for OIIO textures or our own custom texture types. A filename to handle hash map is used for lookups. This is efficient because it happens at OSL compile time, because the optimizer can figure out constant strings and replace them with texture handles.
