                                              R2UnitQuadUsableType in_quad)

Construct a new renderer.

Parameters:

in_g - An OpenGL interface

in_shader_env - Access to shader sources

in_texture_defaults - A set of default textures

in_pool - An ID pool

in_quad - A usable unit quad

Returns:

A new renderer

delete

public void delete(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g3)
            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

renderLights

public void renderLights(R2GeometryBufferUsableType gbuffer,
                         com.io7m.jareas.core.AreaInclusiveUnsignedLType area,
                         Optional<R2LightBufferUsableType> lbuffer,
                         com.io7m.jcanephora.profiler.JCGLProfilingContextType pc,

Description copied from interface: R2LightRendererType

Render the given lights into the given light buffer.

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

Specified by:

renderLights in interface R2LightRendererType

Parameters:

gbuffer - The populated geometry buffer

area - The output viewport

lbuffer - The output light buffer

pc - A profiling context

uc - A texture unit context

shadows - A set of rendered shadow maps

m - A matrix context

s - The opaque lights
