Detailed Description

An infinite fog volume, implemented by drawing at the near plane and ray marching until it hits the depth buffer.

A general implementation for a finite volume would draw at the closest point on the volume that is not past the near plane, in order to get the benefit of early depth testing.

This is not optimized...it just brute-force marches through the volume.

◆ canBeFullyRepresentedInGBuffer()

virtual bool G3D::FogVolumeSurface::canBeFullyRepresentedInGBuffer ( const GBuffer::Specification & specification ) const

inlineoverridevirtual

Can this particular instance of this type of Surface be fully described in a G3D::GBuffer using the given specification?

Often set to false for Surfaces with fractional alpha values, transmission, special back-to-front rendering needs, that require more dynamic range in the emissive channel, or that simply lack a renderIntoGBufferHomogeneous implementation.

Surfaces that return false for canBeFullyRepresentedInGBuffer may still implement renderIntoGBufferHomogeneous for the parts of their surfaces that are representable, and doing so will improve the quality of AmbientOcclusion and post-processing techniques like MotionBlur and DepthOfField.

	)

staticinherited

Computes the world-space bounding box of an array of Surfaces of any type.

		Array< Vector4 > &	packedTangent,
		Array< Point2 > &	texCoord,
		bool	previous = `false`
	)		const

inlinevirtualinherited

Clears the arrays and appends indexed triangle list information.

Many subclasses will ignore previous because they only use that for rigid-body transformations and can be represented by the current geometry and moving coordinate frame. However, it is possible to include skinning or keyframe information in a Surface and respond to timeOffset.

Not required to be implemented.

Reimplemented in G3D::UniversalSurface.

inlinevirtualinherited

Creates and appends Tris and CPUVertexArray::Vertices onto the parameter arrays using the cpuGeom's of the surfaces in surfaceArray.

Invoking this with elements of surfaceArray that are not of the same most-derived type as this will result in an error.

Reimplemented in G3D::UniversalSurface.

◆ hasTransmission()

virtual bool G3D::FogVolumeSurface::hasTransmission ( ) const

overridevirtual

Forward-render all illumination terms for each element of surfaceArray, which must all be of the same most-derived type as this.

Implementations must obey the semantics of the current stencil, viewport, clipping, and depth tests.

Used for z prepass and shadow mapping.

◆ renderDepthOnlyHomogeneous()

virtual void G3D::FogVolumeSurface::renderDepthOnlyHomogeneous	(	RenderDevice *	rd,

	)		const

virtualinherited

Render a set of surfaces from the same most-derived class type.

The default implementation calls render() on each surface.

Parameters

surfaceArray Pre-sorted from back to front and culled to the current camera. Invoking this method with elements of surfaceArray that are not of the same most-derived type as this will result in an error.

		const float	minZSeparation = `0.0f`,
		const LightingEnvironment &	lightingEnvironment = `LightingEnvironment()`
	)

staticinherited

Renders front-to-back to a GBuffer using current stencil and depth operations.

Parameters

sortedVisible	Surfaces that are visible to the camera (i.e., already culled) and sorted from back to front.
previousCameraFrame	Used for rendering GBuffer::CS_POSITION_CHANGE frames.

If depthPeelTexture is not null, then use it and minZSeparation to perform a depth peel. This will result in the depth buffer representing the closest geometry at least minZSeparation behind the geometry in depthPeelTexture.

Parameters

lightingEnvironment Provided even though this method is primarily used for deferred shading to allow objects with partly pre-computed lighting to complete their shading and write directly to the emissive buffer.

◆ renderIntoGBufferHomogeneous()

virtual void G3D::Surface::renderIntoGBufferHomogeneous	(	RenderDevice *	rd,

		const float	minZSeparation,
		const LightingEnvironment &	lighting
	)		const

inlinevirtualinherited

Render all instances of surfaceArray to the currently-bound Framebuffer using the fields and mapping dictated by specification.

This is also used for depth-only (e.g., z-prepass) rendering.

Invoking this with elements of surfaceArray that are not of the same most-derived type as this will result in an error.

If depthPeelTexture is not null, then use it and minZSeparation to perform a depth peel. This will result in the GBuffer representing the closest geometry at least minZSeparation behind the geometry in depthPeelTexture.

Parameters

previousCameraFrame Used for rendering GBuffer::CS_POSITION_CHANGE frames.
