Detailed Description

A class that emulates immediate-mode graphics rendering like older graphics APIs.

An immediate renderer uses an internal OpenGL-like state machine build on top of modern graphics rendering techniques. This style of rendering can be useful for easily drawing debug information or quick prototyping. This renderer should not be used for performance-sensitive rendering.

Constructor & Destructor Documentation

om::graphics::renderers::ImmediateRenderer::ImmediateRenderer ( )

Create a new immediate-mode renderer with no valid context to render to.

om::graphics::renderers::ImmediateRenderer::ImmediateRenderer ( GraphicsContext * newContext )

Create a new immediate-mode renderer which uses the specified graphics context.

virtual

Destroy this immediate renderer and release all associated resources.

Member Function Documentation

Reimplemented from om::graphics::renderers::Renderer.

void om::graphics::renderers::ImmediateRenderer::synchronizeContext ( )

Ensure that the context has the current rendering state for this immediate renderer.

This method should be called before doing any immediate-mode rendering so that the context is ensured to have the same state as what is stored locally as part of the immediate-mode renderer. This information consists of the viewport, scissor viewport, and render mode attributes.
