Auto camera framing of sine wave
Bella scene file writing
Using Diffuse Logic's logging
Using render event callbacks with EngineObserver override
Use of arguments
Adding quickmaterials to the scene
Shows how to wire node output ie belVoxelMat1["color"] |= belColor1.output("outColor");
Using both procedural Bella box and a mesh box modelled from Blender
Hiding boilerplate code like cube mesh and basic Bella scene population in .h files

Usage

poomer-bella-sine #generates a 100 voxel sine plot, output .bsa
poomer-bella-sine -n:1000 # plot 1000 voxels on sine curve
poomer-bella-sine -or:16 # render 16 frames of camera orbit
poomer-bella-sine -sa:60 # sets amplitude
poomer-bella-sine -sf:0.55 # sets sine frequency
poomer-bella-sine -cv:0.65 # sets color variation
poomer-bella-sine -em # sets one material per voxel plot with gradient
poomer-bella-sine -r # render current image
poomer-bella-sine -s:2 # set xfrom scale on voxels to double
poomer-bella-sine -sv # set xfrom scale on voxels using modulus
poomer-bella-sine -m:50 # set modulus event to occur every 50 voxels

[todo] add checks for illegal argument values
