Handmade Math

• v1.11, 05/2020, https://github.com/HandmadeMath/Handmade-Math
• I like the C API, and single-file distribution, but had the following problems
  • no support for matrix inverse
  • troubles building in C++ code, with gcc: error: ISO C++ prohibits anonymous structs [-Werror=pedantic]

applyMatrix on Geometry does not flip faces when needed

applyMatrix, on Geometry or BufferGeometry, does not flip faces indices when applying a matrix that flips normals (determinant < 0).

Based on my looking at ThreeJS r115dev source code, while trying to figure out how to customize the lighting by writing my own shader.

Materials

ThreeJS has the following Material classes :

• MeshBasicMaterial, not affected by lights
• MeshLambertMaterial: lighting is computed at each vertex, for diffuse lighting, and interpolated in gouraud like fashion

Once more, I'm struggling to wrap my head around the threejs API, here are my notes.

IMPORTANT base on threejs r114 (march 2020)

API topics covered :

• Scene and Object3D, hierarchy, transforms
• Maths, linear algebra
• DirectionalLight, as I'm currently trying to understand how to attach one of them to a Camera...

Cycles

I had crashes while scripting the CUDA devices selection (b3d v2.83 + 4x GTX 2080 GPU).

The original code was :

preferences = bpy.context.preferences
cycles_preferences = preferences.addons["cycles"].preferences
cuda_devices, opencl_devices = cycles_preferences.get_devices()
