Detailed Description

A stock renderer provided as a basic utility and an example.

Draws a grid in the scene.

Member Function Documentation

void sv::GridRenderer::InitializeGL ( )

overridevirtual

Override to acquire OpenGL resources required by the Renderer.

At the time this method is invoked, the following are true:

It is guaranteed that this method will be called exactly once, and before any call to RenderBegin().

Reimplemented from sv::Renderer.

void sv::GridRenderer::RenderBegin ( )

overridevirtual

Called at the start of rendering, just before the scene is rendered.

When this method is called, the following are true:

No shader programs are active (i.e., glUseProgram(0) has been called)
The projection matrix (GL_PROJECTION) is setup according to the active camera.
The modelview matrix stack has a single matrix on it that correspnods to the camera view matrix.
The GL_MODELVIEW matrix stack is active.
OpenGL lights have been configured according to the lights in the scene graph.

In other words, the matrix stack is setup such that you can render in "world" coordinates.

You can issue legacy fixed-function OpenGL commands (e.g., glColor3f(), glBegin(), glVertex3f(), etc. calls)

You can also use your own vertex and fragment shaders.

Reimplemented from sv::Renderer.
