Member Enumeration Documentation

enum Wizt::SplatRenderObject::Renderer::mode

The rendering parameters for the point sets.

Enumerator:

accumulative	Just add colors accumulative.
depthsorted	Do rendering via depth-sorting (might be slow).
alphaclamped	Do rendering via alpha-clamping.
accumulative_absorption	Do two-pass rendering, absorption first, then emission.

Mode for alpha clamping.

Default is GEQUAL .

Specifies the alpha comparison function. Symbolic constants GL_NEVER, GL_LESS, GL_EQUAL, GL_LEQUAL, GL_GREATER, GL_NOTEQUAL, GL_GEQUAL, and GL_ALWAYS are accepted.

double Wizt::SplatRenderObject::Renderer::AlphaThreshold

Treshold for alphaclamped mode.

Default is 0.5 .
