Method Detail

makeCurrent

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

Description copied from interface: TechniqueDefLogic

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

Specified by:

makeCurrent in interface TechniqueDefLogic

Overrides:

makeCurrent in class DefaultTechniqueDefLogic

Parameters:

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

updateLightListUniforms

protected int updateLightListUniforms(Shader shader,
                                      Geometry g,
                                      LightList lightList,
                                      int numLights,
                                      RenderManager rm,
                                      int startIndex)

Uploads the lights in the light list as two uniform arrays.

*

uniform vec4 g_LightColor[numLights];
// g_LightColor.rgb is the diffuse/specular color of the light.
// g_Lightcolor.a is the type of light, 0 = Directional, 1 = Point,
// 2 = Spot.

uniform vec4 g_LightPosition[numLights];
// g_LightPosition.xyz is the position of the light (for point lights)
// or the direction of the light (for directional lights).
// g_LightPosition.w is the inverse radius (1/r) of the light (for attenuation)

render

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

Description copied from interface: TechniqueDefLogic

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.

Specified by:

render in interface TechniqueDefLogic

Overrides:

render in class DefaultTechniqueDefLogic

Parameters:

renderManager - The render manager to perform the rendering against.

shader - The shader that was selected by this logic in TechniqueDefLogic.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.
