addAttributesDivisor0

protected abstract void addAttributesDivisor0(com.badlogic.gdx.utils.Array<com.badlogic.gdx.graphics.VertexAttribute> attributes)

Adds the required vertex attributes for this renderer to the given list. These attributes are added only once for all instances (divisor=0)

Parameters:

attributes - The list of attributes with divisor=0

addAttributesDivisor1

protected abstract void addAttributesDivisor1(com.badlogic.gdx.utils.Array<com.badlogic.gdx.graphics.VertexAttribute> attributes)

Adds the required vertex attributes for this renderer to the given list. These attributes are added for every instance (divisor=1)

Parameters:

attributes - The list of attributes with divisor=1

buildAttributesDivisor0

protected com.badlogic.gdx.graphics.VertexAttribute[] buildAttributesDivisor0()

Builds the vertex attributes with divisor=0 array and returns it

Returns:

The vertex attributes array

buildAttributesDivisor1

protected com.badlogic.gdx.graphics.VertexAttribute[] buildAttributesDivisor1()

Builds the vertex attributes with divisor=1 array and returns it

Returns:

The vertex attributes array

offsets0

protected abstract void offsets0(ImmediateModeRenderSystem.MeshData curr)

Computes the offset for each vertex attribute. The offsets will be used later in the render stage.

Parameters:

curr - The current mesh data

offsets1

protected abstract void offsets1(ImmediateModeRenderSystem.MeshData curr)

Computes the offset for each vertex attribute in the instanced array. The offsets will be used later in the render stage.

Parameters:

curr - The current mesh data

addMeshData

protected int addMeshData(int maxVerts0,
 int maxVerts1)

Adds a new mesh data to the meshes list and increases the mesh data index

Parameters:

maxVerts0 - The max number of vertices the divisor 0 mesh data can hold

maxVerts1 - The max number of vertices the divisor 1 mesh data can hold

Returns:

The index of the new mesh data

preRenderObjects

protected void preRenderObjects(ExtShaderProgram shaderProgram,
 ICamera camera)

renderObject
