Visualization

The library uses wgpu, egui, winit for visualization.

Example

use env_logger::Builder;
use glam::{Mat4, Vec3};
use log::{info, LevelFilter};
use tessellate::gpu::options::{CameraOptions, GpuOptions, LightOptions};
use tessellate::mesh::material::{Color, RgbaColor};
use tessellate::mesh::transform::Transform;
use tessellate::mesh::{HasMesh, Mesh, MeshError};
use tessellate::{files, gpu, TessError, TessResult};
use tobj::LoadOptions;

fn main() -> TessResult<()> {
    let path = "examples/import_models/cow.obj";
    let mut cow = files::obj::import_obj(path, &LoadOptions::default())?;
    let meshes = vec![cow];
    let options = GpuOptions::default();
    Ok(gpu::visualize(meshes, options)?)
}

Components

Camera

The visualization gives the option to rotate,shift, scale the scene. The manipulations are performed around the center of the scene where the center is the centroid of the bounding box of the scene. The initial position for the camera is set from the configurations.

Light

The light affects the surfaces for the objects in the scene. The light is set from the configurations. Every mesh has a set of light properties that can be set.

Axes

The axes are drawn in the scene to give a sense of direction. The axes are drawn on the corner of the bounding box of the scene.

UI

The UI is used to control the camera and light properties. The UI is drawn using egui.
