Member Function Documentation

void StelQGL2InterleavedArrayVertexBufferBackend::draw	(	class StelQGL2Renderer &	renderer,
		const Mat4f &	projectionMatrix,
		class StelQGLIndexBuffer *	indexBuffer,
		class StelQGLGLSLShader *	shader
	)

Draw the vertex buffer, optionally with index buffer specifying which indices to draw.

Called by StelQGL2Renderer::drawVertexBufferBackend().

Parameters

renderer	Renderer that created this buffer.
projectionMatrix	Projection matrix (column major) used for drawing.
indexBuffer	If NULL, all vertices in the buffer are drawn in the order they are stored. If not NULL, specifies indices of vertices to draw.
shader	Shader used for drawing, with any needed projection/transform shaders enabled.

The documentation for this class was generated from the following file:
