Texcoords and Precision<br />
• 10 bits of mantissa is enough <strong>to</strong><br />
exactly address a 1024-wide texture<br />
– With no filtering<br />
• 10 bits can do a 512-wide texture<br />
with 2 filtering levels<br />
• So, large textures may require high<br />
precision <strong>to</strong> sample with good<br />
filtering
