Kumikaya 9a2eb878a2 Fix underflow panic in InitTriInfo (#14893) ... # Objective - Fix #14874 ## Solution - Change the place where a panic occurs from `t < iNrTrianglesIn - 1` to `t + 1 < iNrTrianglesIn`. ## Testing - After the fix, the following code runs successfully without any panic. ```rust use bevy::prelude::Mesh; use bevy_render::{ mesh::{Indices, PrimitiveTopology}, render_asset::RenderAssetUsages, }; const POSITIONS: &[[f32; 3]] = &[[0.0, 1.0, 0.0], [0.0, 0.0, 0.0], [0.0, 1.0, 0.0]]; const NORMALS: &[[f32; 3]] = &[[0.0, 0.0, 0.0], [0.0, 0.0, 0.0], [0.0, 0.0, 0.0]]; const INDICES: &[u32] = &[0, 1, 2]; const UVS: &[[f32; 2]] = &[[0.0, 1.0], [0.0, 0.0], [0.0, 1.0]]; fn main() { let mut mesh = Mesh::new( PrimitiveTopology::TriangleList, RenderAssetUsages::default(), ); mesh.insert_attribute(Mesh::ATTRIBUTE_POSITION, POSITIONS.to_vec()); mesh.insert_attribute(Mesh::ATTRIBUTE_UV_0, UVS.to_vec()); mesh.insert_attribute(Mesh::ATTRIBUTE_NORMAL, NORMALS.to_vec()); mesh.insert_indices(Indices::U32(INDICES.to_vec())); mesh.generate_tangents().ok(); } ``` ## Migration Guide - No breaking changes introduced.		2024-08-25 14:13:23 +00:00
