kiss3d

Keep It Simple, Stupid 3d graphics engine.

This library is born from the frustration in front of the fact that today’s 3D graphics library are:

• either too low level: you have to write your own shaders and opening a window steals you 8 hours, 300 lines of code and 10L of coffee.
• or high level but too hard to understand/use: those are libraries made to write beautiful animations or games. They have a lot of feature; too much feature if you only want to draw a few geometries on the screen.

kiss3d is not designed to be feature-complete or fast. It is designed to be able to draw simple geometric figures and play with them with one-liners.

An on-line version of this documentation is available here.

Features

Most features are one-liners.

• open a window with a default arc-ball camera and a point light.
• a first-person camera is available too and user-defined cameras are possible.
• display boxes, spheres, cones, cylinders, quads and lines.
• change an object color or texture.
• change an object transform (we use the nalgebra library to do that).
• create basic post-processing effects.

As an example, having a red, rotating cube with the light attached to the camera is as simple as:

```rust extern crate native; extern crate kiss3d; extern crate nalgebra;

use nalgebra::na::Vec3; use kiss3d::window::Window; use kiss3d::light;

[start]

fn start(argc: int, argv: *const *const u8) -> int { native::start(argc, argv, main) }

fn main() { let mut window = Window::new("Kiss3d: cube"); let mut c = window.add_cube(1.0, 1.0, 1.0);

c.set_color(1.0, 0.0, 0.0);

window.set_light(light::StickToCamera);

while window.render() {
    c.prepend_to_local_rotation(&Vec3::new(0.0f32, 0.014, 0.0));
}

} ```

Some controls are handled by default by the engine (they can be overridden by the user):

• scroll: zoom in / zoom out.
• left click + drag: look around.
• right click + drag: translate the view point.
• enter: look at the origin (0.0, 0.0, 0.0).

Compilation

You will need the last nightly build of the rust compiler and the official package manager: cargo.

Simply add the following to your Cargo.toml file:

[dependencies.kiss3d] git = "https://github.com/sebcrozet/kiss3d"

Contributions

I’d love to see people improving this library for their own needs. However, keep in mind that kiss3d is KISS. One-liner features (from the user point of view) are preferred.
