HipVertexArrayObject

For using this class, you must first define the vertex layout for after that, create the vertex buffer and/or the index buffer.

class HipVertexArrayObject {

IHipVertexArrayImpl VAO;

IHipVertexBufferImpl VBO;

IHipIndexBufferImpl EBO;

uint dataCount;

HipVertexAttributeInfo[] infos;

bool isBonded;

bool hasVertexInitialized;

bool hasIndexInitialized;

static bool putQuadBatchIndices(index_t[] output, size_t countQuads);

void createIndexBuffer(index_t count, HipBufferUsage usage);

void createVertexBuffer(uint count, HipBufferUsage usage);

HipVertexArrayObject appendAttribute(uint count, HipAttributeType valueType, uint typeSize, string infoName, bool isPadding);

HipVertexArrayObject appendAttribute(string infoName, bool isPadding);

void sendAttributes(Shader s);

void unbind();

void setVertices(void[] data);

void updateVertices(void[] data, int offset);

void setIndices(index_t[] data);

void updateIndices(index_t[] data, int offset);

static HipVertexArrayObject getVAO();

}

Functions

appendAttribute HipVertexArrayObject appendAttribute(uint count, HipAttributeType valueType, uint typeSize, string infoName, bool isPadding): This function creates an attribute information, for later sending it(it is necessary as the stride needs to be recalculated)
appendAttribute HipVertexArrayObject appendAttribute(string infoName, bool isPadding): Undocumented in source. Be warned that the author may not have intended to support it.
bind void bind(): Undocumented in source. Be warned that the author may not have intended to support it.
createIndexBuffer void createIndexBuffer(index_t count, HipBufferUsage usage): Creates and binds an index buffer.
createVertexBuffer void createVertexBuffer(uint count, HipBufferUsage usage): Creates and binds a vertex buffer.
sendAttributes void sendAttributes(Shader s): Sets the attribute infos that were appended to this object. This function must only be called after binding/creating a VBO, or it will fail
setIndices void setIndices(index_t[] data): Will set the indices data. Beware that this function may allocate memory.
setVertices void setVertices(void[] data): Sets the VBO data. Use this function only for initialization as it allocates memory.
unbind void unbind(): Undocumented in source. Be warned that the author may not have intended to support it.
updateIndices void updateIndices(index_t[] data, int offset): Updates the index buffer's data. It won't allocate memory
updateVertices void updateVertices(void[] data, int offset): Update the VBO. Won't cause memory allocation.

Static functions

getVAO HipVertexArrayObject getVAO(): Receives a struct and creates a VAO based on its member types and names.
putQuadBatchIndices bool putQuadBatchIndices(index_t[] output, size_t countQuads): Populates a buffer with indices forming quads Returns if the output can contain the size
