gpu_get_ztestenable

This function can be used to retrieve whether z-testing is enabled (the function returns true) or not (the function returns false). The default value is that z-testing is disabled, so the function will return false.

Syntax:

gpu_get_ztestenable();

Returns:

Boolean

Example:

if (gpu_get_ztestenable() == false)
{
    gpu_set_ztestenable(true);
}

The above code checks to see if z-testing is enabled or not and if it is disabled it is then enabled again.
