WebOpenGL has several fuctions for matrix transformations; glTranslatef (), glRotatef () and glScalef (). Matrix4 class provides the equivalent functions to transform matrix; translate (), rotate () and scale () respectively. In addition, Matrix4 provides invert () to compute a inverse matrix. Webnpm install glsl-basic-vertex-shader usage Inside your vertex shader just call #pragma glslify: main = require ('glsl - basic - vertex - shader') components Make sure you define all attributes and uniforms. If you don't need to use any of the matrices just set them to the identity matrix. The varying variables can be used in your fragment shader. bocchi outdoors╱ボッチアウトドア https://mayaraguimaraes.com
