Detailed Description

template<T>
class Derm::Render::RenderBufferObject< T >

Generic buffer object.

Template Parameters:

T

This type shall be one the base type of each element stored in the RenderBufferObject. This type shall be a structured type, but there are some limitation (they are dictated from the OpenGL Shading Language specification). In the current implementation the type T shall be: Vertex1f (that's a float) Vertex2f Vertex3f Vertex4f Vertex1i (that's a signed integer) Vertex2i Vertex3i Vertex4i Missing unsigned integer types Additionally T can be any structure which each member is typed with one of the previously mentioned types; keep in mind that the structure shall be declared with the [StructLayout(LayoutKind.Sequential, Pack = 1)] attribute. Specifying a kind of structure like described above allow to pack different data types into an unique RenderBufferObject, enhancing the data access since per-vertex data is localized better than using different RenderBufferObject instances.

Constructor & Destructor Documentation

template<T >

Derm.Render.RenderBufferObject< T >.RenderBufferObject	(	int	type,
		UsageMode	dUsage,
		XferMode	dMode
	)			[protected]

RenderBufferObject constructor.

Parameters:

	type	The RenderBufferObject type could assume one of the values: Derm.Gl.ARRAY_BUFFER Derm.Gl.ELEMENT_ARRAY_BUFFER Derm.Gl.PIXEL_PACK_BUFFER Derm.Gl.PIXEL_UNPACK_BUFFER Derm.Gl.UNIFORM_BUFFER
	dUsage	An UsageMode specifying the data buffer usage.
	dMode	A XferMode specifying the data buffer transfer mode.

Construct a generic RenderBufferObject.

Member Function Documentation

template<T >

override void Derm.Render.RenderBufferObject< T >.AllocateOnClient

(

int

items

)

[virtual]

Allocates RenderBufferObject data on client.

Parameters:

items

Number of items to allocate. A System.Int32

It simply allocates buffer data. The initial value of the data is determined by the type parameter T.

Implements Derm.Render.BufferObject.

template<T >

void Derm.Render.RenderBufferObject< T >.AllocateOnClient	(	T[]	data,
		bool	copy
	)

Allocates/Set RenderBufferObject data on client.

Parameters:

	data	Buffer source data array. A T
	copy	Flag indicating whether caller wants to make a copy of data or simply take the reference or array. A System.Boolean

It defines this RenderBufferObject data. The data is reallocated in the case the parameter copy is false; in this case later modifications to the refence data
