void glm_mat4_mulN (mat4 * __restrict matrices[], int len, mat4 dest) ¶ mupliply N mat4 matrices and store result in dest | this function lets you multiply multiple (more than two or more) | matrices. multiplication will be done in loop, this may reduce instructions. size but if len is too small then compiler may unroll whole loop. mat m1, m2, m3, m4, res; glm_mat4_mulN ((mat4 * []){& m1. mat4 m; m[1] = vec4(2.0); // sets the second column to all 2.0 m[0][0] = 1.0; // sets the upper left element to 1.0 m[2][3] = 2.0; // sets the 4th element of the third column to 2.0 Remember, OpenGL defaults to column major matrices, which means access is of the format mat[col][row]. In the example, m[2][3] sets the 4th ROW (index 3) of the 3rd COLUMN (index 2) to 2.0. In the example m[1]=vec4. gl-mat4 . Part of a fork of @toji's gl-matrix split into smaller pieces: this package contains glMatrix.mat4.. Usage. mat4 = require('gl-mat4') Will load all of the module's functionality and expose it on a single object. Note that any of the methods may also be required directly from their files glm::mat4 constructor that takes only a single value constructs a diagonal matrix: . glm::mat4 m4( 1.0f ); // construct identity matrix The matrix has all zeros except for 1.0f set along the diagonal from the upper-left to the lower-right.. The default constructor glm::mat4() creates diagonal matrix with 1.0f diagonal, that is, the identity matrix

Which means, the normal way we would do this with a glm::mat4 would be like: GLint uniView = glGetUniformLocation(shaderProgram, view); glUniformMatrix4fv(uniView, 1, GL_FALSE, glm::value_ptr(view)); since we are not using glm::mat4 datatypes, would it be fine.

  1. Tutorial 13 : Normal Mapping. Welcome for our 13th tutorial ! Today we will talk about normal mapping. Since Tutorial 8 : Basic shading, you know how to get decent shading using triangle normals.One caveat is that until now, we only had one normal per vertex : inside each triangle, they vary smoothly, on the opposite to the colour, which samples a texture
  2. Unfortunately, there is still no way to draw with GL_LINE_STRIP, because the index array also cannot tell OpenGL where to start and end the line strips. But we can draw with GL_LINES! Now, you may think that then we have a lot of duplication again, because we would have to draw a line from vertex index 0 to 1, from 1 to 2, and so on. However, indices are small numbers, usually one or two bytes.
  3. $\begingroup$ In setting the color of the texture in transformValueToColor(), you set the alpha value to 255 * (1 - tValue), which means that as long as tValue is not 1.0, will be somewhere between 0 and 255. An alpha value that is not 255 will produce a non-opaque (or semi-transparent) pixel - one you can see through. My point was that if the front-most geometry is semi-transparent, you must.
