MB3D 1.99 release: improved point-cloud export
Just released MB3D V1.99 with improved point-cloud export.
I thought it may be already time for a new release, as there are some really major improvemens
on point-cloud-export, and I’m not sure how many spare time I will find in the next weeks for further additions.What’s new:
– Point-Cloud-export:
– major increase of sampling-quality
– minor speed-increase (is compensated by generating more samples)
– jitter-option to improve sampling of round shapes, usually gives good results at high volumetric resulutions > 1000
– option to generate normal vectors (is not the same as approximating the normals on the final mesh)
– display elapsed time
– Progressbar for the BulbTracer-preview
– renamed the “MeshGen”-button back to “BulbTracer” (which was always the intended name)
– updated the huge JIT-formula.pack (“EM_JIT_M3Formulas”) from Alef from fractalforums.com
– Added the missing formulas to the distribution: JosKn-KleinIFS, JosKn-ModIFS, K-TowerIFSCheers!

MB3D 1.98 release: point-cloud export
Just released MB3D V1.98 with point-cloud export.
Even if I stopped active development of MB3D a while ago, I make some additions from time to time.
Now there are enough features finished to make a new release (coming even more close to V2.00 ;-)).
What’s new:
– Point-Cloud-export in the BulbTracer-module, which is able to generate very nice models in high resolution in a short time,
even with color (which is currently a limited feature).
This mode is now the default mode in the BulbTracer, with a initial volumetric resolution of 256, which is nice to play around,
because it is not too slow, but often creates nice models.
For creating a final mesh, a volumetric resolution of 2560 is not unusual, as the new mode is fast and takes not too much memory.To use the old way of generating mesh consiting of vertices and faces, choose “Mesh” as Mesh Type)
– updated the huge JIT-formula.pack (“EM_JIT_M3Formulas”) from Alef from fractalforums.comHave fun!

JWildfire 3.20 release: point-cloud export
Just released JWildfire V3.20 – which is another community release, thanks to Brad, Rick and Luca for your contributions!
This is a major release featuring a new kind of mesh-export: point-clouds. Point-clouds basically are meshes with 1-point-polygons.
In contrast to the solid meshes, the “points” of the generated point-clouds may have also an individual color and an alpha channel
(which may be used in rendering).3D-Packages like Houdini can render point-clouds in the way that each point is represented by a little sphere
(you usually can adjust the size of those spheres), generating a “solid” shape.
You can apply materials to point-clouds like to any regular mesh. Especially in Houdini, the points keep their individual
(diffuse) color.You can also generate “solid” meshes from point-clouds, for example using the ball-pivoting-algorithm inside
MeshLab.Important Parameters for point-cloud-generation in JWildfire (use “Output type” POINTCLOUD to enable it):
- CELL-SIZE: the program uses an octree to quantize the space into little small cubes. All samples inside a cube
are later condensed into one point of the point-cloud. So, this setting basically affects the
“resolution” of the generated mesh. But beware, please make it only smaller in small steps,
otherwise memory consumption may grow in an “explosive” way - RENDER QUALITY: overall number of samples, increase it only if your mesh has noise/holes in it
- OUTPUT FORMAT: you may either use *.ply or *.obj. But beware, this option has also an impact on the generation
of the point-cloud:- PLY-Format: only vertices (“points”), with color and alpha channel (works good for Houdini)
- OBJ-Format: vertices and 1-point-polygons, NO color and NO alpha channel (works good for Lightwave Hypervoxels)
Complete list of changes (you can also see this list inside the program at the any time, see Help->List of changes ):
- New “POINTCLOUD”-generator inside the Mesh-Generator.
