addAttributesDivisor0

protected void addAttributesDivisor0(com.badlogic.gdx.utils.Array<com.badlogic.gdx.graphics.VertexAttribute> attributes,
 int posArraySize,
 boolean useNormals,
 boolean useTexCoords)

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

posArraySize - Size of the position array (2 or 3).

useNormals - Add normal attributes as a vector-3.

useTexCoords - Add texture coordinates attribute as a vector-2.

addAttributesDivisor1

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

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

primitive - The rendering primitive.

buildAttributesDivisor0

protected com.badlogic.gdx.graphics.VertexAttribute[] buildAttributesDivisor0(int posArraySize,
 boolean useNormals,
 boolean useTexCoords)

Builds the vertex attributes with divisor=0 array and returns it. The content of divisor-0 attributes is updated in each iteration of the vertex shader.

Parameters:

posArraySize - Size of the position array (2 or 3).

useNormals - Add normal attributes as a vector-3.

useTexCoords - Add texture coordinates attribute as a vector-2.

Returns:

The vertex attributes array

buildAttributesDivisor1

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

Builds the vertex attributes with divisor=1 array and returns it The content of divisor-1 attributes is updated for each instance.

Parameters:

primitive - The rendering primitive.

Returns:

The vertex attributes array.

offsets0

protected abstract void offsets0(ImmediateModeRenderSystem.MeshData curr,
 InstancedRenderSystem.InstancedModel model)
