What could be the reason for OpenGL 4.6 batch rendering not producing any output?

edit

There could be several reasons why OpenGL 4.6 batch rendering is not producing any output. Some common reasons include:

1. Incorrect initialization of OpenGL context: It is important to properly initialize the OpenGL context and make sure that all required extensions and features are enabled.

2. Incorrect use of buffer objects: If the buffer objects used for batch rendering are not set up correctly, it may lead to no output being produced. Make sure to properly allocate, bind and fill the data in buffer objects.

3. Incorrect use of shaders: If the shaders used to render the batches are not set up correctly, it may lead to no output. Make sure to set the appropriate vertex attribute pointers, vertex shader input variables, and fragment shader output variables.

4. Incorrect use of rendering commands: If the rendering commands used to draw the batches are not set up correctly, it may lead to no output. Make sure to properly configure blending, culling, and depth testing and use the appropriate draw commands.

5. Hardware limitations: If the hardware being used does not support OpenGL 4.6 or lacks the necessary extensions, it may not be possible to produce output using batch rendering.
