BLENDER VIEWPORT 3D TEXTURING

Project goal:

Provide a proof of concept of 3D texturing the mesh in Blender Viewport based on the below details. Both mesh and texture are strictly defined spatially: origin, spacing and size are provided. Texturing is to be properly displayed during mesh editing operations (real-time preview). Texture is to be displayed according to the provided colormap with the possibility of UI/programmable changes.

Project is to be used in medical applications and hence the values mapped onto the surface have to be precise (i.e., they are not to look good, but rather to provide actual information visually).

Inputs:

  • Mesh provided as a STL file.

  • 3D texture derived from a VTI volume provided as an MHD, 16-bit TGA or a PNG 2D “mosaic” (volume slices arranged next to each other). Example:

drive.google.com/file/d/1prA2svAcoVvitVvn2D2IsqFQJztJF00-/view

  • Colormap provided as a 2D texture. Example:

drive.google.com/file/d/1D6CXcnVwRTDzBryRJJvSYNOAhJIEe7vB/view Or a set of RGB values (optional): github.com/matplotlib/matplotlib/blob/4f42c6825fe311f18812f99701701cb484da7670/lib/matplotlib/_cm_listed.py

Output:

  • Full BLEND project with potential dependencies.

Output example:

  • Created with 3DCoat ( 3dcoat.com ) taking advantage of the explicit use of shaders: youtu.be/GjIduo0oBJE

    Notice how mesh (blood vessel) texturing is changing during mesh modification (1:40-2:40). Pixel color values come directly from the volume (Computed Tomography of the blood vessel vicinity) values in the corresponding location.

Addendum:

  • Blender version: 2.82 is preferred but not obligatory.

  • Use of any 3rd party free/paid software/plugins may be allowed but has to be consulted.

Completion time: Flexible (individual consultation)

Fee: US$ 1000
