Construct a new renderer.

Parameters:

in_g - An OpenGL interface

in_shader_env - A shader preprocessing environment

in_pool - An ID pool

Returns:

A new renderer

renderMask

public void renderMask(com.io7m.jareas.core.AreaInclusiveUnsignedLType area,
                       Optional<R2MaskBufferUsableType> mbuffer,
                       com.io7m.jcanephora.profiler.JCGLProfilingContextType pc,

Description copied from interface: R2MaskRendererType

Render the given instances into the given mask buffer.

If a mask buffer is provided, it will be bound before evaluation and left bound after the method returns.

Specified by:

renderMask in interface R2MaskRendererType

Parameters:

area - The output viewport

mbuffer - The optional mask buffer

pc - A profiling context

tucp - A texture unit context

m - A matrix context

s - The mask instances

            throws R2Exception

Description copied from interface: R2DeletableType

Delete the current object.

Specified by:

delete in interface R2DeletableType

Parameters:

g3 - An OpenGL interface

Throws:

R2Exception - On errors

isDeleted

public boolean isDeleted()

Specified by:

isDeleted in interface com.io7m.jcanephora.core.JCGLResourceUsableType
