Update to the Optimizer

The optimizer now evaluates the stones using:

  1. Light return for tilted positions
  2. Light return for different view angles
  3. Scintillation

The weights used to get a final score are 45%, 45%, 10%. This results is a single number ranging from 0 to 100: the Hackagem score.

Scintillation Graphs

Hackagem extends the analysis tab: it now measures the scintillation for tilted positions and shows the results in a graph.

Path Tracer

Path tracing is an extension of ray tracing used for realistic rendering. While ray tracing simulates light paths by tracing rays from the camera to light sources, path tracing goes further by simulating the complex behavior of light as it bounces around a scene. It randomly samples multiple light paths per pixel, accounting for global illumination, reflections, refractions, and diffuse lighting. This stochastic approach produces highly realistic images but are computationally expensive due to the need for many samples to reduce noise.

2024-11-30 New preform outlines

For instance there is the Double-truncated Rectangle to get smooth corners. A double-truncated rectangle starts as a rectangle with all four corners truncated, forming an octagon. This octagon is then truncated again at its corners, resulting in a 16-sided polygon with smoothed edges, featuring four original sides shortened by truncations and 12 additional edges created through the two stages of corner cuts All outlines.

2024-10-25 Truncated Triangles

Added CAM support for the creation of truncated triangles. If you are interested in how this works, below is the code. Getting the correct angle for PF2 took a bit of thinking… 

function createTruncatedTriangle(c, angle) {
    let d = 0.7 // closest distance of the girdle to the center
    let e = d * Math.sqrt(3) // half the base
    let h = Math.tan(deg2rad(angle)) * d
    let f = Math.sqrt(e * e + d * d) // Pythagoras
    let beta = rad2deg(Math.atan(h / ((1.0 - c / 2) * f)))
    let n = getIndexGear()
    cut("PF1", range(0, n / 3), angle, centerPoint())
    cut("PF2", range(n / 6, n / 3), beta, centerPoint())
    cut("G1", range(0, n / 3), 90, d)
    cut("G2", range(n / 6, n / 3), 90, level())
}
