Detailed Description

Stores a list of textures, each with its own texture handle. This allows the textures to be stored separately from the objects, which allows multiple objects to share the same textures.

Invariant

_imagePointers.Invariant(), invariant of each image in the arrray

Member Function Documentation

void GlsTexturePalette::BindTexture	(	GlsStateManager &	gl,
		const GlsUInt32	index
	)		const

Bind the texture at the given index, unless it is already bound. Set as the texture to be used for texturing polygons

Parameters

gl	OpenGL State Manager to bind texture in
index	index < GetSize(), index != NO_TEXTURE, entry at index is not GLS_NULL

Precondition

index < GetSize(), index != NO_TEXTURE, entry at index is not GLS_NULL

Postcondition

texture at given index is bound to OpenGL
