You will have to describe in more detail how this feature should work, and illustrate it with images. Or supply an example .blend file showcasing the Cycles subdivision.

In my opinion, Subdiv + Simplify is a very poor substitute for real adaptive subdivision. The difference in memory requirement and compute time is immense. So I would also welcome...

Stuff I found which might be useful: OpenImageIO has a function for rendering text: [implementation](https://github.com/OpenImageIO/oiio/blob/81ea41cb76a84f4b21d294e2bd1400c8a16bd499/src/libOpenImageIO/imagebufalgo_draw.cpp#L787) [python unittest example](https://github.com/OpenImageIO/oiio/blob/7933b6b9aec27fcdf19877455897ca049e121019/testsuite/python-imagebufalgo/src/test_imagebufalgo.py#L442) [usage in oiiotool](https://github.com/OpenImageIO/oiio/blob/master/src/oiiotool/oiiotool.cpp#L4094)

Good suggestion, I have something like this on my list since a while but did not find time for it yet. Some comments: > * [ ] Absolute Value This...

You can look at the commits I made when I added the HSV texture: https://bitbucket.org/luxrender/luxrays/commits/all?search=hsv You need the header and source files for the texture, the parsing code in `src/slg/scene/parsetextures.cpp`,...

A question for @Dade916: Since we are planning to add a lot of textures with rather simple operations, should we go a different route and put all of these operations...

> Could you make a custom math node, where user could type in his/her own equation? You mean that the user types in a string? That would be possible, but...

I added a remap texture in commit cce9953a2d73738c3d1a70d9c797c12610b4a842.

By the way, @Dade916: How should we add vector operations? Currently there are only interfaces for `float` and `Spectrum` datatypes, not `Vector`. Should it be added as a new function...

Spectrum is a typedef for RGB color in LuxCore currently: https://github.com/LuxCoreRender/LuxCore/blob/master/include/luxrays/core/color/color.h#L470
