WebMar 25, 2024 · Then I tried flipping the vertex indices and I realized that if I created the second triangle counter-clockwise like so. geometry.setIndex([ 0, 1, 2, // first triangle 2, 3, 1 // instead of 2,1,3 ]); this will actually flip the face so that the camera would now be facing the back side of the second triangle. Web来自BufferGeometry的文档： index (itemSize: 3) Allows for vertices to be re-used across multiple triangles; this is called using"indexed triangles," and works much the same as it does in Geometry: each triangle is associated with the index of three vertices. This attribute therefore stores the index of each vertex for each triangular face.

WebOnce you transformed (projected) your 3D coordinates in the view/camera space, your X and Y coordinates are the 2D triangle corners/vertices coordinates (let's assume you decided that X goes from left to right, Y goes from top to bottom, this is quite common).
