The SetIndexRange method is used to define a specific range of indices within a mesh. This method allows you to specify a starting index and a count of indices to be used, effectively setting a sub-range of the mesh's index buffer. This can be useful for rendering a specific portion of a mesh or for optimizing rendering by only processing a subset of the mesh's indices.
To use the SetIndexRange method, you need to provide two parameters:
start: An int representing the starting index in the mesh's index buffer.count: An int representing the number of indices to include in the range.Ensure that the specified range is within the bounds of the mesh's index buffer to avoid runtime errors.
// Example of using SetIndexRange Mesh myMesh = new Mesh(); // Assuming the mesh has been properly initialized and has an index buffer int startIndex = 0; int indexCount = 100; // Set a range of indices to be used myMesh.SetIndexRange(startIndex, indexCount);
