GLRENDERBUFFERHEIGHT

GLRENDERBUFFERHEIGHT is a constant or symbolic name used within graphics programming, specifically related to the OpenGL (Open Graphics Library) API. It is associated with the manipulation and querying of renderbuffers. Renderbuffers are off-screen buffers that store image data, often used for various rendering targets like depth or stencil information, or as intermediate storage for rendering operations.

When working with renderbuffers in OpenGL, developers can set various properties to define their behavior and size. GLRENDERBUFFERHEIGHT specifically refers to the height dimension of a renderbuffer. This property is typically set when creating or resizing a renderbuffer, or it can be queried to determine its current height. Understanding and controlling the height of a renderbuffer is crucial for ensuring that rendering operations fit within the allocated buffer space and for managing memory efficiently.

The exact usage of GLRENDERBUFFERHEIGHT would involve calls to OpenGL functions. For instance, a function like glGetRenderbufferParameteriv might be used to retrieve the current height of a bound renderbuffer, passing GLRENDERBUFFERHEIGHT as an argument to specify which parameter is being requested. Conversely, a function like glRenderbufferStorage might be used to allocate storage for a renderbuffer, where its dimensions, including height, would be provided as parameters. The value associated with GLRENDERBUFFERHEIGHT is an integer representing the number of pixels in the vertical dimension.
