Member Function Documentation
◆ getShaderDefines()
|
static |
Defines shader functions to compute indices and coordinates for a vertex ID.
Given a field named Positions , the following shader functions are provided:
// Multidimensional index for the linear vertex index I
ivec3 Eval_Positions_Index(int I);
// Coordinates for the given vertex id
vec3 Eval_Positions(int I);
// Coordinates for the given vertex id relative to the Origin of this uniform array
vec3 Eval_Relative_Positions(int I);
Usually a vertex shader will call these functions for a given
gl_VertexID
Note this functionality requires GLSL version 130 or better for gl_VertexID and
#extension GL_EXT_gpu_shader4 : enable
to enable usage of the modulo operator. For instance, in constructors derived from class Programmable, do
v_prefix = "#version 130\n"
"#extension GL_EXT_gpu_shader4 : enable\n"
;
◆ NumberOfElements()
|
overridevirtual |
Returns the number of elements provided and used by this object, if it refers to countable elements.
Otherwise, returns 0 (default).
Reimplemented from Wizt::Anemone::Tentacle.
