Method Details

getRenderGroup

public RenderGroup getRenderGroup()

Specified by:

getRenderGroup in interface IRenderSystem

render

public void render(List<IRenderable> renderables,
 ICamera camera,
 double t,
 RenderingContext rc)

Description copied from interface: IRenderSystem

Renders the given list of renderable objects.

Specified by:

render in interface IRenderSystem

Parameters:

renderables - The list of objects to render.

camera - The camera object.

t - The time, in seconds, since the session start.

rc - The rendering context object.

renderStud

public abstract void renderStud(List<IRenderable> renderables,
 ICamera camera,
 double t)

addPreRunnables

public void addPreRunnables(AbstractRenderSystem.RenderSystemRunnable... r)

addPostRunnables

public void addPostRunnables(AbstractRenderSystem.RenderSystemRunnable... r)

run

protected void run(com.badlogic.gdx.utils.Array<AbstractRenderSystem.RenderSystemRunnable> runnables,
 List<IRenderable> renderables,
 ICamera camera)

getAlpha

public float getAlpha(IRenderable renderable)

Computes the alpha opacity value of a given renderable using its component types

Parameters:

renderable - The renderable

Returns:

The alpha value as the product of all the alphas of its component types.

getAlpha

public float getAlpha(com.badlogic.ashley.core.Entity entity)

getAlpha

public float getAlpha(ComponentTypes ct)

resize

public void resize(int w,
 int h)

Description copied from interface: IRenderSystem

Resize the current render target with the given width and height.

Specified by:

resize in interface IRenderSystem

Parameters:

w - The new width.

h - The new height.

updateBatchSize

public void updateBatchSize(int w,
 int h)

Description copied from interface: IRenderSystem

Updates the size of object batches, if any.

Specified by:

updateBatchSize in interface IRenderSystem

Parameters:

w - The new width.

h - The new height.

addEffectsUniforms

protected void addEffectsUniforms(ExtShaderProgram shaderProgram,
 ICamera camera)

addVRScale

protected void addVRScale(ExtShaderProgram shaderProgram)

addRelativisticUniforms

protected void addRelativisticUniforms(ExtShaderProgram shaderProgram,
 ICamera camera)

addGravWaveUniforms

protected void addGravWaveUniforms(ExtShaderProgram shaderProgram)

addDepthBufferUniforms

public void addDepthBufferUniforms(ExtShaderProgram shaderProgram,
 ICamera camera)

Uniforms needed to compute the logarithmic depth buffer. They never change, so only add if not present.

Parameters:

shaderProgram - The program.

camera - The camera.

addCameraUpCubemapMode

protected void addCameraUpCubemapMode(ExtShaderProgram shaderProgram,
 ICamera camera)

Adds the camera up vector (only in non-cubemap mode) to compute the billboard rotation. In regular mode, we use the camera up vector to have screen-aligned billboards. In cubemap mode(s), we use a global up direction.

Parameters:

shaderProgram - The program.

camera - The camera.

getShaderProgram

protected ExtShaderProgram getShaderProgram()

getShaderProgram

protected ExtShaderProgram getShaderProgram(ExtShaderProgram[] programs)

initShaderProgram

protected void initShaderProgram()

Initializes metadata or essential uniforms in the shader program.

dispose

Specified by:

dispose in interface com.badlogic.gdx.utils.Disposable

resetFlags

public void resetFlags()

compareTo

public int compareTo(IRenderSystem o)

Specified by:

compareTo in interface Comparable<IRenderSystem>
