VertexBufferObject

Buffer is a object oriented wrapper for a Vertex Buffer Object. VertexRenderer is public imported. See there for more details, like PointerTarget.

class VertexBufferObject {

Target targets;

ubyte numTargets;

this(Target trg, Type type);

void bind(Target trg);

void unbind();

Target getBound();

bool isSomethingBound();

bool isCurrentEmpty();

bool isEmpty(Target trg);

void deplete();

void depleteAll();

void cache(void* ptr, size_t totalSize, uint usage);

void modify(void* ptr, size_t totalSize, uint offset);

void* map(Access access);

void unmap();

void pointTo(Target trg, ubyte stride, ubyte offset);

void enableState(Target trg);

void enableAllStates();

void disableAllStates();

void disableState(Target trg);

void drawArrays(Shape.Type ptype, size_t count, uint start);

void drawElements(Shape.Type ptype, size_t count, uint[] indices);

void drawRangeElements(Shape.Type ptype, size_t count, uint[] indices, int start, int end);

void bindTexture(Texture tex);

}

Constructors

this this(Target trg, Type type): CTor

Members

Enums

Access enum Access: The access type.
Type enum Type: Declare which Buffer Type is stored.

Functions

bind void bind(Target trg): Binds the a specific VBO PointerTarget. If the target is invalid (because no such buffer exist) nothing happens.
bindTexture void bindTexture(Texture tex): Bind a texture to this Buffer. It's a shortcut for:
cache void cache(void* ptr, size_t totalSize, uint usage): Stores data in the current VBO.
deplete void deplete(): Reset the current buffer state
depleteAll void depleteAll(): Reset all buffer states
disableAllStates void disableAllStates(): Disable all client states
disableState void disableState(Target trg): Disable a specific client state (with glDisableClientState)
drawArrays void drawArrays(Shape.Type ptype, size_t count, uint start): Draw shapes of the specific type from the current VBO data. It will use count vertices.
drawElements void drawElements(Shape.Type ptype, size_t count, uint[] indices): Draw shapes of the specific type from the current VBO data. It will use count vertices and indices for the correct index per vertex.
drawRangeElements void drawRangeElements(Shape.Type ptype, size_t count, uint[] indices, int start, int end): Draw shapes of the specific type from the current VBO data. It will use count vertices and indices for the correct index per vertex.
enableAllStates void enableAllStates(): Enable all client states
enableState void enableState(Target trg): Enable a specific client state (with glEnableClientState) like GL_VERTEX_ARRAY, GL_COLOR_ARRAY, GL_TEXTURE_COORD_ARRAY with the corresponding PointerTarget.
getBound Target getBound(): Returns the current PointerTarget
isCurrentEmpty bool isCurrentEmpty(): Checks whether the current buffer has already content, or not
isEmpty bool isEmpty(Target trg): Checks whether a specific buffer has already content, or not. If the target is invalid (because no such buffer exist) an Exception is thrown.
isSomethingBound bool isSomethingBound(): Returns if some PointerTarget is currently bound
map void* map(Access access): The internal buffer memory is transferred to the memory of the client with a specific access. Before the buffer can be reused, <code>unmap</code> must be called.
modify void modify(void* ptr, size_t totalSize, uint offset): Modify existing buffer data
pointTo void pointTo(Target trg, ubyte stride, ubyte offset): Points to the current VBO with a specific PointerTarget.
unbind void unbind(): Unbind the current VBO.
unmap void unmap(): Allows other commands buffer access, in which it retrieves the memory from the client.
