Detailed Description
Regular grid rendering algorithm.
- Date
- Feburary, 2019
Renders a regular grid by ray tracing. The CPU side just loads the scalar data and missing values as well as secondary data if needed
The glsl code does a standard sampled ray tracing of the volume.

On OSX, some shaders can run for a long time without problems while others will crash if the run too long. It seems to correlate with complexity. Chunked rendering splits the rendering into smaller tasks so they won't crash
