Normal maps are uv mapped images with constant resolution bump map can be procedural texture computed at rendering time with infinite resolution dependent on camera zoom.
Normal mat vs bump.
Like bump mapping it is used to add details to shading without using more polygons.
In the end a normal map does create the illusion of depth detail on the surface of a model but it does it differently than a bump map.
Bump maps are converted to normal maps by gpu cpu or by user.
Normal maps and height maps are not the same thing.
Normal maps are faster to render than procedural bump maps because of lack of conversion and finite resolution.
The question is as per tittle.
Normal vs bump map ehy guys.
While bump mapping perturbs the existing normal the way the surface is facing of a model normal mapping replaces the normal entirely.
Can anyone tell me when i should use normal maps vs bump maps or do i use them both at the same time when texturing an item etc.
June 2016 in technical help nuts n bolts hi all i am texturing out my first product with bump maps and came across normal maps.
Now in vred it looks like both work.
In 3d computer graphics normal mapping is an application of the technique known as bump mapping.
Though it could be argued that bump map and height map are the same thing you could consider a normal map to instead be the derivative with respect to x stored in red channel and y stored in green channel of the bump map.
To create a material with a bump is it better to use a bump map or a normal map.
