ChuGL geometries contain vertex data such as positions, normals, and UV coordinates.
Base geometry class, do not instantiate directly.
Geometry()
Default constructor for Geometry.
Geometry clone()
Clone the geometry, including all attributes.
void colors(float[] colors)
Set color attribute data from an array of floats; every 4 floats corresdpond to (r, g, b, a) values of a vertex color);.
void colors(vec3[] colors)
Set color attribute data from an array of vec3 (r, g, b); alpha is assumed to be 1.0.
void colors(vec4[] colors)
Set color attribute data from an array of vec4 (r, g, b, a)
void indices(int[] indices)
Sets vertex indices for indexed drawing. If not set, renderer will default to non-indexed drawing.
void normals(float[] normals)
Set normal attribute data from an array of floats; every 3 floats corresdpond to (x, y, z) values of a vertex normal.
void normals(vec3[] normals)
Set normal attribute data from an array of vec3 (x, y, z)
void positions(float[] positions)
Set position attribute data from an array of floats; every 3 floats correspond to (x, y, z) values of a vertex position.
void positions(vec3[] positions)
Set position attribute data from an array of vec3 (x, y, z)
void setAttribute(string name, int location, int numComponents, float[] data)
Set the attribute data for the given attribute location, to be passed into the vertex shader. Builtin attribute locations are POS_ATTRIB_LOC, NORM_ATTRIB_LOC, COL_ATTRIB_LOC, UV0_ATTRIB_LOC.
void uvs(float[] uvs)
Set UV attribute data from an array of floats; every pair of floats corresponds to (u, v) values (used for texture mapping)
void uvs(vec2[] uvs)
Set UV attribute data from an array of vec2 (u,v) or (s,t)
