Octopus-VDMs are high resolution vector displacement
maps that are generated from detailed photogrammetry scans containing
several million triangles. All VDMs undergo an optimization
algorithm resulting in minimal stretch and clean topology with very low
distortion, even for complex shapes with overhangs. The vector displacement maps have a resolution of 2048 x 2048 and come with a color texture of the same size.
What you get
To celebrate the start of the project I am happy to release these 8 vector displacement map assets for free under the creatve commons license. Try them out to see if they fit your workflow and quality requirements and If you like them, check out my other VDM packages.
Each VDM is provided in two verions:
- The original version that directly corresponds to the 3D-scanned geometry.
- A flattened version with zero displacement at the borders which is better suited for sculpting.
all VDMs come with a texture derived from color calibrated photos that
perfectly fit the geometry. Note, that in Blender there is currently no
good way to apply VDMs with textures in sclupting mode so they are
primarily useful for geometry node setups.
What is special about Octopus-VDMsUnlike most VDMs available, Octopus-VDMs are directly computed from 3D-scanned geometry and thus provide high detail, color and subtle imperfections only found in nature.
Computing VDMs from
unstructured input meshes with arbitrary topology, bridges and potential
holes is no easy task and required custom software specifically
developed for this project. The core algorithm converts an
input mesh with tens of millions of triangles to a deformed regular
grid of size 2048 x 2048 from which the final VDM can be computed.
During the computation the grid is optimized to have low
distortion and even sampling.
