Interface TechniqueDefLogic

All Known Implementing Classes:

DefaultTechniqueDefLogic, MultiPassLightingLogic, SinglePassAndImageBasedLightingLogic, SinglePassLightingLogic, StaticPassLightingLogic

public interface TechniqueDefLogic

TechniqueDefLogic is used to customize how a material should be rendered. Typically used to implement lighting modes. Implementations can register unmapped defines in their constructor and then later set them based on the geometry or light environment being rendered.

Method Summary

Modifier and Type	Method and Description
Shader	makeCurrent(AssetManager assetManager, RenderManager renderManager, java.util.EnumSet<Caps> rendererCaps, LightList lights, DefineList defines) Determine the shader to use for the given geometry / material combination.
void	render(RenderManager renderManager, Shader shader, Geometry geometry, LightList lights, int lastTexUnit) Requests that the TechniqueDefLogic renders the given geometry.

Method Detail

makeCurrent

Shader makeCurrent(AssetManager assetManager,
                   RenderManager renderManager,
                   java.util.EnumSet<Caps> rendererCaps,
                   LightList lights,
                   DefineList defines)

Determine the shader to use for the given geometry / material combination.

Parameters:

assetManager - The asset manager to use for loading shader source code, shader nodes, and lookup textures.

renderManager - The render manager for which rendering is to be performed.

rendererCaps - Renderer capabilities. The returned shader must support these capabilities.

lights - The lights with which the geometry shall be rendered. This list must not include culled lights.

defines - The define list used by the technique, any unmapped defines should be set here to change shader behavior.

Returns:

The shader to use for rendering.

render

void render(RenderManager renderManager,
            Shader shader,
            Geometry geometry,
            LightList lights,
            int lastTexUnit)

Requests that the TechniqueDefLogic renders the given geometry. Fixed material functionality such as RenderState, material parameters, and uniform bindings have already been applied by the material, however, RenderState, uniforms, textures, can still be overridden.

Parameters:

renderManager - The render manager to perform the rendering against.

shader - The shader that was selected by this logic in makeCurrent(com.jme3.asset.AssetManager, com.jme3.renderer.RenderManager, java.util.EnumSet, com.jme3.light.LightList, com.jme3.shader.DefineList).

geometry - The geometry to render

lights - Lights which influence the geometry.

lastTexUnit - the index of the most recently used texture unit
