8 Bit Vs 16 Bit Displacement Maps

In V1.03 I've added the 16 bit support. What is this?

The JPG image format is widely spread but it's only 8 bit per color (8 for red, 8 for green and 8 for blue, total = 24 bit). When it comes to coding depth, it's really limited by its 8 bit nature, it has only 256 steps.

While 256 steps are invisible for most 3D textures, they are obvious when it comes to modelling high polygon 3d objects. (See left image with 400 000 triangles)

Using 16 bit instead (like in 16bit Tiff format) gives a far better result.

Now with v1.03, you can actually store all depth data of the photosculpt object winthin a single 16 bit tiff displacement map.

The new function is located in "Menu/File/Save displacement as 16 bit tiff". Try it today, it's also available in the 30 day trial demo now.
