Public Member Functions | |
| virtual uint32_t | getVertexCount () const =0 |
| Returns the number of vertices in the buffer. | |
| virtual const VertexFormat & | getFormat () const =0 |
| Returns the data format. See VertexFormat. | |
| virtual VertexFormat & | getFormatWritable ()=0 |
| Returns the data format. See VertexFormat. Can be changed. | |
| virtual const void * | getBuffer (uint32_t bufferIndex) const =0 |
| Accessor for the data buffer indexed by bufferIndex. To get the buffer format, use getFormat().getBufferFormat( index ). If the data channel doesn't exist then this function returns NULL. | |
| virtual const void * | getBufferAndFormat (RenderDataFormat::Enum &format, uint32_t bufferIndex) const =0 |
| Like getBuffer(), but also returns the buffer's format. | |
| virtual void * | getBufferAndFormatWritable (RenderDataFormat::Enum &format, uint32_t bufferIndex)=0 |
| Like getBuffer(), but also returns the buffer's format. Can be changed. | |
| virtual bool | getBufferData (void *dstBuffer, nvidia::RenderDataFormat::Enum dstBufferFormat, uint32_t dstBufferStride, uint32_t bufferIndex, uint32_t startVertexIndex, uint32_t elementCount) const =0 |
| Accessor for data in a desired format from the buffer indexed by bufferIndex. If the channel does not exist, or if it is in a format for which there is not presently a converter to the the desired format dstBufferFormat, this function returns false. The dstBufferStride field must be at least the size of the dstBufferFormat data, or zero (in which case the stride is assumed to be the size of the dstBufferFormat data). If neither of these conditions hold, this function returns false. Otherwise, dstBuffer is filled in with elementCount elements of the converted data, starting from startVertexIndex, withe the given stride. | |
