2020-04-01Cycles: AVX implantation of Perlin noise.OmarSquircleArt
This patch adds an AVX implementation of Perlin noise in Cycles. An avxi type was also added as a utility based on the respective type in Intel Embree. Only 3D and 4D noise were implemented, there is no benefit for utilizing AVX in 1D and 2D noise. The SSE trilinear interpolation function was used in the AVX implementation because there is no benefit from using AVX in interpolating the last three dimensions.

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

2019-09-05Fix: Compile error due to undefined isinf function.OmarSquircleArt
Some implementations of the standard c++ library doesn't define its functions in the global namespace. So the `isinf` function might fail in some systems. To fix this, we use the `ensure_finite` function instead. Reviewers: brecht Differential Revision: https://developer.blender.org/D5687
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.

2019-08-26GPencil: Invert Paste operator and make Paste to Active defaultAntonio Vazquez
Before there were two options: Paste to original layer called "Paste" and Paste to active layer called "Paste & Merge" Now, by default the paste is in active layer and the "Paste & Merge" has been renamed "Paste". For old "Paste", now is called "Paste by Layer" and it's not the default value anymore. Note: Minor edits to add icons not present in Differential revision.

2019-08-21Shading: Add White Noise node.OmarSquircleArt
The White Noise node hashes the input and returns a random number in the range [0, 1]. The input can be a 1D, 2D, 3D, or a 4D vector. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5550

2014-01-08Cycles: workaround for noise performance regression in CUDA 5.5Sv. Lockal
Use manual ternary operation widening in grad(). Without it nvcc 5.5 produces multiple branch splits with very big branches (because of inlining). This solves 19% performance regression for BMW1M-MikePan.blend. Also remove one redundant instruction in perlin SSE (when h == 12 or h == 14, then h is always >= 4).

2013-11-18Cycles: change __device and similar qualifiers to ccl_device in kernel code.Brecht Van Lommel
This to avoids build conflicts with libc++ on FreeBSD, these __ prefixed values are reserved for compilers. I apologize to anyone who has patches or branches and has to go through the pain of merging this change, it may be easiest to do these same replacements in your code and then apply/merge the patch.
