Rendering is the art of converting a 3d model to a good looking 2d picture or video.
Blender can be used for world-class rendering. It is completely free and can be obtained from blender
Once blender is installed a scene can be exported to blender directly by pressing the cute blender icon:
The Base Scene#
The Blender model starts with the blender base model that is included with DAVE.
By default this is a file called “base ocean.blend” which is located in the highest resource path.
The base scene contains
a material called “Cable” which is used for exported cables and
a material called “Ocean” which is used for exported waves
It is possible to start with another base scene. This can be changed by either:
Using the GUI
passing another file-name as argument to the
BLENDER_BASE_SCENEvariable (defined in settings.py)
All visuals are exported to Blender. All visuals in DAVE are either .obj or .stl files.
During the export DAVE looks for a file with the same name but with the .blend extension. If such a file is found through the resources system then that file is imported. If such a file is not found then the .obj or .stl is used.
This means that for a workflow with a nicely rendered result it is advised to
create your visuals in blender
apply all transforms by hitting A (select all) and then Ctrl+A –> All Transforms
keep the high resolution blender file with shaders, textures, etc. somewhere in a resource path
export a lower resolution .obj for use in DAVE. Use Y forward and Z up during export.
