* math: Rewrite vector math library to use packed f64 bytevectors.David Thompson2016-02-274-141/+303
| | | | | | | | | | | | | | | | | | | | The big consequence of this change to the rest of the codebase is that we can no longer use record destructuring when pattern matching, so I had to rewrite every place where pattern matching was used. It was probably a bad idea to expose the record type descriptors publicly in the first place. * sly/math/vector.scm: Reimplement everything in terms of an f64 packed bytevector record type. Do not expose record type descriptors. * sly/game.scm (run-game-loop): Convert viewport width/height to exact numbers. * sly/window.scm (open-window): Likewise. * sly/input/mouse.scm (mouse-position): Rewrite pattern matching. * sly/math/quaternion (make-quaternion, vector->quaternion): Likewise. * sly/math/rect.scm (rect-clamp): Likewise. * sly/math/transform.scm (translate!, translate, scale): Likewise. * sly/render/mesh.scm (vertices-bytevector): Likewise. * examples/mines/mines.scm: Likewise.
* math: transform: Perform matrix multiplication in Scheme.David Thompson2016-02-111-8/+136
| | | | | | | | No more GSL dependency! Thanks Andy Wingo, for unboxed floating point operations! * sly/math/transform.scm (matrix-ref, matrix-set!): Allow inlining. (transform*!): Reimplement in pure Scheme, no FFI call to GSL.
* math: rect: Fix rect-inflate implementation.David Thompson2016-01-011-2/+2
| | | | | * sly/math/rect.scm (%rect-inflate): Subtract, not add, the half width. D'oh!
* Optimize matrix operations.David Thompson2015-08-251-39/+52
| | | | | | | | | | | | | | | | | | | | | Guile's array procedures are slow, so switch to using raw bytevectors instead. Additionally, converting the bytevector to a pointer is also slow, so the pointer is now cached for redundant calls. There's more to be done, but this was low hanging fruit. * sly/math/transform.scm (<transform>)[ptr]: New field. (transform-ptr): New accessor. (set-transform-ptr!): New setter. (make-4x4-matrix): Implement using bytevectors. (matrix-set!, matrix-ref): New procedures. (make-transform, transform-vector2, transform-position): Use 'matrix-set!' and 'matrix-ref'. (transpose, transform+, transform*): Use new transform constructor. (transform->pointer): Cache pointer. * sly/render/context.scm (copy-transform!): Use 'bytevector-copy!' * sly/render/shader.scm: Use 'transform->pointer' in the transform uniform setter.
