Xatlas source code parsing (7)

About the one-write function on the xatlas interface:

It's been a while, some functions I just rememberProbably, first record it in the follow-up supplement, otherwise you will forget it.

Pack input mesh uvs: Use the uv coordinates of the model itself, and recalculate the uv coordinates if not checked;

The chart options in the left sidebar are some parameters about each chart, and the chart is each color block on the right.

weight: some weight values ​​set when calculating the chart, the calculation process will refer to these weights;

Max chart area: The area limit of each chart (the sum of the triangle areas in the chart);

Max boundary length: the length of the quadrilateral of each chart;

Pack options in the sidebar on the left is a packaged atlas, which expands the uv of the model into multiple images, each of which is an atlas.

Bilinear: The triangles in each chart will be interpolated on the two-dimensional array image in memory, and the interpolation method is linear interpolation;

Block align: block alignment, whether to place each chart horizontally or vertically;

Texels per uint: The number of textures per unit, similar to dpi, the checkerboard in 3DMax modeling;

Resolution: The resolution of each atlas, the pictures are square;

pading: The spacing between charts in each atlas;

Max chart size: Limit the size of one chart in each chart. If the chart is larger than this size, the chart will be scaled to this size;
