splatviz-blender

Blender addon for gaussian splatting rendering.

splatviz-blender.mp4

tmp.mp4

Used composite.blend file to render this video. Two scene in the blend file. One for 3dgs render and one for eevee or cycles render, and composite based on depth and alpha images. Objects in scenes are linked, so pute objects in splatviz render engine scene will also show in eevee or cycles scene. The composition nodes in composite.blend should work.

Things this addon can do:

• render 3dgs
• use depth and alpah images to composite 3dgs and other mesh objects render.
• camera animation

Things this addon cannot do:

• edit 3dgs
• render 3dgs and other mesh objects at the same time in viewport mode. (viewport composition using two render engine (two render layers) is not supported now in blender. Seems this feature will be supported in future blender version.)
• change camera fov

This blender addon is based on splatviz.
