README
Polyform is for loading, generating, editing, and exporting 3D geometry and it's associated data.
Overview
Modeling
meshops - All currently implemented algorithms for transforming meshes.
marching - Multi-threaded Cube Marching algorithm and utilities.
extrude - Functionality for generating geometry from 2D shapes.
repeat - Functionality for copying geometry in common patterns.
primitives - Functionality pertaining to generating common geometry.
triangulation - Generating meshes from a set of 2D points.
colors - Making working with golang colors not suck as much.
curves - Common curves used in animation like cubic bezier curves.
geometry - AABB, Line2D, Line3D, Plane, and Rays.
noise - Utilities around noise functions for common usecases like stacking multiple samples of perlin noise from different frequencies.
quaternion - Quaternion math and helper functions
sample - Serves as a group of definitions for defining a mapping from one numeric value to another
sdf - SDF implementations of different geometry primitives, along with common math functions. Basically slowly picking through Inigo Quilez's Distfunction article as I need them in my different projects.
Generator - Application scaffolding for editing and creating meshes
Trees - Implementation of common spatial partitioning trees.
Packages that have spawned from polyform's undertaking and have since been refactored into their own repositories:
vector - Immutable vector math library
jbtf - GLTF-inspired JSON schema for embedding arbitrary binaries
iter - Iterator and utilities. Some inspiration from ReactiveX
quill - Scheduler of operations on in-memory data
sfm - Utilities for interacting with reconstruction data from different SFM programs
bitlib - Utilities for reading and writing binary data
Procedural Generation Examples
You can at the different projects under the examples folder for different examples on how to procedurally generate meshes.
Evergreen Trees
This was my submission for ProcJam 2022. Pretty much uses every bit of functionality available in this repository.
Other Examples
Developing
If you so happen to want to build a configurator example, my preferred workflow is:
Set up the example to use the generator
package that allows you to quickly spin up a web viewer to visualize the geoemetry of your program.
Use air to live reload the examples as you build them out. Set cmd = "go build -o ./tmp/main.exe ./examples/MY_EXAMPLE"
. Set include_ext = ["go", "tpl", "tmpl", "html", "js"]
.
As you hit save on your go code, the webserver will restart, and the web page will automatically refresh itself.
If you want to mess with modern web browser features and need https, I recommend taking a look at https://github.com/FiloSottile/mkcert
WASM Dev
Compile the polywasm
app
Then build your example app
Processing Example
Reads in a obj and applies the cube marching algorithm over the meshes 3D SDF.
