List of all members.

Detailed Description

Create with EffectManager::CreateVertexBuffer(). A vertex buffer needs to be bound to enable rendering and unbound afterwards. You may use glDrawArrays and glArrayElement to draw from vertex buffer or use aditionally a index buffer to render indexed primitives.

virtual unsigned long	GetSize ()=0
virtual const VertexComponent *	GetFormat ()=0
virtual void *	Lock (GLenum access)=0
virtual void	Unlock ()=0

Member Function Documentation

virtual unsigned long GLFX::IVertexBuffer::GetSize

(

)

[pure virtual]

Returns number of vertices.

Returns:

number of vertices

virtual const VertexComponent* GLFX::IVertexBuffer::GetFormat

(

)

[pure virtual]

Returns vertex format.

Returns:

vertex format

virtual void* GLFX::IVertexBuffer::Lock

(

GLenum

access

)

[pure virtual]

Locks vertex buffer and returns pointer to memory.

Parameters:

access

access mode (GL_READ_ONLY, GL_WRITE_ONLY, or GL_READ_WRITE); 0 -- default access mode (write only)

virtual void GLFX::IVertexBuffer::Unlock

(

)

[pure virtual]

Unlocks vertex buffer. Memory pointer returned by Lock() is no longer valid.

virtual void GLFX::IVertexBuffer::Bind

(

)

[pure virtual]

Enable client state and set pointers.

virtual void GLFX::IVertexBuffer::Unbind

(

)

[pure virtual]

Disables rendering from this vertex buffer.
