Detailed Description

Contains all of the data needed to render a model.

A RenderSet contains a list of all of the vertices in a GModel. For each vertex, it gives the position, surface normal, and texture coordinates. These lists are all strided arrays and can be interleaved. Interleaving your arrays can increase performance.

The RenderSet also contains a list of indices forming triangles, lines, or points.

Member Enumeration Documentation

enum GAUGE3D::GModel::RenderInfo::RenderSet::tDynamicFlags

Specifies which properties of the model are dynamic. Remarks: Typically, vertex positions and normals are dynamic (if anything). Enumeration values: STATIC   Model is not dynamic. VERTEX_POSITION   Vertex positions (and normals) are dynamic. VERTEX_TEXCOORD   Vertex texture coordinates are dynamic. INDEX_LIST   Index list is dynamic.

enum GAUGE3D::GModel::RenderInfo::RenderSet::tIndexType

Specifies how to make geometry out of the indices. Enumeration values: POINTS   Every indice is a point / particle. LINES   Every two indices make one line segment. TRIANGLES   Every three indices make one triangle.

Member Function Documentation

void GAUGE3D::GModel::RenderInfo::RenderSet::SetDefaults ( ) [inline]

Called by the renderer to reset the RenderSet. Remarks: The idea is that older model plugins may not support newer RenderSet data fields. In order to make sure the renderer does not read uninitialized data from those fields, they are set to some default value. This is all for binary and source code backwards compatibility, but also makes writing model plugins easier.
