kandi X-RAY | proctree Summary

proctree is a C library typically used in Editor applications. proctree has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This is a liberally licensed procedural tree generator in c++, along with an editor HappyTree. The procedural generation itself is a port from see for an online demonstration of the original proctree.js (with webgl). The c++ port is several orders of magnitude faster than the original, and also fixes the UV mapping.

Properly scaling textures in three.js / proctree.js

Three.js texture alignment/scaling with proctree.js

QUESTION

Properly scaling textures in three.js / proctree.js

Asked 2019-Jul-30 at 22:29

Apologies for the vague title, I'm not sure how to describe my issue.

I'm trying to create a forest in three.js with the very cool proctree.js. The library seems to create a 3d model of the tree's trunk and main branches, then adds simple flat textures for the leaves (or 'twigs').

The resulting tree looks very nice from up close but as you zoom out the leaves visually disappear almost entirely. This is a problem as I'm trying to create a dense looking forest. See the following two screengrabs (or this online viewer):

Is there a way to prevent the leaves from becoming very pixelated and thin looking from a distance? Or, to phrase the question differently, how would one create good-looking leaves that look as dense from a distance as they do from up close?

The material used looks like this:

Your problem sounds very similar to this one

I'm pretty certain that the smaller-resolution mipmaps (when you zoom out) are blending your leaf textures and changing the alpha values to which the alphaTest threshold compares to. The further away you are, the more area of your texture is considered "transparent".

You can modify your texture properties as follows to disable mipmaps:

QUESTION

Three.js texture alignment/scaling with proctree.js

Asked 2017-Dec-28 at 01:40

I'm trying to render a model created by SnappyTree/Proctree ( http://www.snappytree.com/ ).

I found this question, that showed how to render the trunk geometry using Three.js instead of proctree.js's author's GLGE project. I've got that working now but the texture on the twigs (branches) doesn't align properly. Any ideas how to make the texture fit on?

This is how the material is created:

Nice tree.

To fix the texturing, first update the proctree.js to three.js conversion code to use the tree.uvsTwig array, instead of tree.UV, for the twigs:

Install proctree

Download win32 binaries at: http://iki.fi/sol/zip/happytree_20150123.zip. Additional (not mandatory) 400 megs of trunk / twig textures http://iki.fi/sol/zip/happytree_20150118_tex.zip. If you opt to download the additional textures, just unzip both zips in the same place. HappyTree will work without the additional textures (it'll actually be faster), so if you're just trying it out, I recommend NOT downloading the additional stuff. All of the textures are CC0 / public domain material (primarily, if not completely, by nobiax.deviantart.com). The additional textures do let you make more varieties of trees though; the base package only comes with one trunk and twig texture. The happytree editor requires OpenGL 3.3, but seriously, who doesn't have that?. Usage should be pretty intuitive, you can rotate the camera by dragging and zoom in and out with the mouse wheel.
