glm-rotate clj

(glm-rotate matrix angle [x y z :as axis])

Builds a rotation 4 * 4 matrix created from an axis vector and an angle. matrix - Input matrix multiplied by this rotation matrix. angle - Rotation angle expressed in radians. axis - Rotation axis, normalized.

glm-scale clj

(glm-scale matrix [x y z :as v])

Builds a scale 4 * 4 matrix created from 3 scalars. matrix - Input matrix multiplied by this scale matrix. v - Ratio of scaling for each axis.

glm-translate clj

(glm-translate matrix [x y z :as v])

Builds a translation 4 * 4 matrix created from a vector of 3 components. matrix - Input matrix multiplied by this translation matrix. v - Coordinates of a translation vector.

look-at clj

(look-at camera)

(look-at camera-pos camera-target up)

Create a view matrix.

mat4 clj

(mat4)

Generates a 4x4 identity matrix.

perspective-fov clj

(perspective-fov)

(perspective-fov fovy aspect-ratio near-plane far-plane)

Create a perpective projection matrix. FOV is in radians. See: mat4#perspective https://glmatrix.net/docs/mat4.js.html

project clj

(project projection view model [x y z :as point])

Convenience function to perform vertex transformation. Performs viewport transformation and perspective division, i.e. divides by the w value and normalizes to [0, 1].

translate clj deprecated

(translate matrix v)

Use glm-translate instead.
