get the perspective-corrected model-to-view matrix

📅 published 7.44.0, from nixpkgs unstable

🎀 NAME 🎀

pmodel2view — from the nged manual, bestie. It gets the perspective-corrected model-to-view matrix. Slay. 💅

✨ SYNOPSIS ✨

pmodel2view

💖 DESCRIPTION 💖

Okay so pmodel2view returns the current perspective-corrected model-to-view transformation matrix as a 16-element space-separated floating-point string. Literally the whole matrix, in one cute little line. ✨

This matrix combines the standard model-to-view transformation with the perspective projection, making it the complete transform that maps a point from model space into perspective view space in one step. Iconic behavior, no cap. 🦋

It is a read-only accessor — the matrix is computed and maintained automatically by the view system and cannot be set directly with this command. So don’t try to make it do something it’s not meant to do, bestie. 🙈

This command takes no arguments. Providing any argument returns a usage error. Periodt. 💀

For the model-to-view matrix without perspective applied, use model2view. For the perspective projection matrix alone, use pmat. Iykyk. 🫶

🌸 EXAMPLES 🌸

⭐ Example 1. Retrieve the perspective-corrected model-to-view matrix

mged> pmodel2view

Returns the 16-element perspective-corrected model-to-view matrix. When no perspective is active, this is equivalent to the model2view matrix. Easy peasy. 💖

🦋 Example 2. Compare with and without perspective

mged> perspective 0
mged> pmodel2view
mged> perspective 45
mged> pmodel2view

The first call returns the orthographic model-to-view matrix. After enabling a 45° perspective, the second call returns the same rotation but with perspective distortion applied. It’s giving “same girl, new angle.” 💅✨
