Interface ISubGLRenderer<T>

Type Parameters:

T - Class of object this renderer draws.

All Known Implementing Classes:

GLRendererCollection, MapRenderer, UTAgentSubGLRenderer

public interface ISubGLRenderer<T>

This is a subrenderer, it's job is to render some stuff. Basically I had few GLEventListeners and there were troubles with using them directly (order of rendering), so I have now only these subrenderes that are part of GLRendererCollection.

Method Summary

Methods

Modifier and Type	Method and Description
List<BlendTriangle>	getBlendedTris() Because blending phase of rendering can be done only after all opaque objects has been drawn and because polys has to be back-to-front ordered every renderer will return list of its blended triangles so final renderer can sort all blended triangles from all blended renderers and do it correctly.
T	getObject() Return object this renderer draws.
void	prepare(javax.media.opengl.GL gl) Here should be done preparation for rendering (e.g.
void	render(javax.media.opengl.GL gl) Display stuff you want to.

Method Detail

prepare

void prepare(javax.media.opengl.GL gl)

Here should be done preparation for rendering (e.g. generation of display lists from massive data)

Parameters:

gl -

render

void render(javax.media.opengl.GL gl)

Display stuff you want to. Assume that settings have already been set in GLRendererCollection

Parameters:

gl -

getObject

T getObject()

Return object this renderer draws. Because objects we want to draw can change rapidly, we have to remove and add subrenderers based on passed objects (renderer R draws object A, now we don't want to draw A anymore, we have to go through subrenderers to find which ones draws it).

Returns:

Object this renderer draws.

getBlendedTris

List<BlendTriangle> getBlendedTris()

Because blending phase of rendering can be done only after all opaque objects has been drawn and because polys has to be back-to-front ordered every renderer will return list of its blended triangles so final renderer can sort all blended triangles from all blended renderers and do it correctly.

Returns:

List of blended triangles this renderer wants to render. Empty collection if no such exists.
