Detailed Description

A Vertex Buffer Render object for making splats.

Member Enumeration Documentation

mode

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.
alphaToCoverage	Alpha to coverage (dithering)
accumulative_absorption	Do two-pass rendering, absorption first, then emission.

Member Data Documentation

AlphaClampMode

GLenum Wizt::SplatRenderObject::Renderer::AlphaClampMode

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.

AlphaThreshold

double Wizt::SplatRenderObject::Renderer::AlphaThreshold

Treshold for alphaclamped mode.

Default is 0.5 .
