Changelog for geomancy

0.3.0.0

[0] releases without row/col-major, handedness, and counter/clockwise confusion.

This release brings sanity and consistency around the transform stack.

• Transforms have proper col-major definitions.
• Operation ordering follows the GLSL convention.
  • The composition order is (p <> v <> m <> ...) (from global to local). Reverse your transforms to adjust.
  • The application order is m !* v (with the operators becoming infixr 5, just under the <>). It will do Mᵀ * v inside for SIMD reasons and to match what GLSL does for its M * v ops.
• Geomancy.Vulkan.Projection is right-handed, BUT produces reverse-depth range ([1; 0], In 3D infinite-Z converges to 0).
  • Replace your depth tests with OP_GREATER and clear to 0.0 - get better precision for your migration troubles.
• Geomancy.Vulkan.View is right-handed, with +Z being forward.
  • The intended up vector is still vec3 0 (-1) 0 -- +Y down. Silly as it sounds, this matches the XY plane of the window with XY plane in front of a "first person" camera.
• Axis rotations (using rotateQ) will appear clockwise when looking along the axis.
• Angle rotations follow Tait-Bryan angles (heading/elevation/bank or yaw/pitch/roll) in the y-x-z frame.
  • rotateZ (time * rate) will follow the clock hands in 2D scenes and roll in 3D.
  • rotateX will follow the sun from sunrise to sunset, pitching UP / increasing elevation.
  • rotateY will turn you right, increasing yaw / heading eastwards.
• You're of course free to define your own transforms, just copy the modules and tune to your liking. Just make sure that you use matching row/column constructors and the math layer will do the rest, fast.
• Added webcolor-labels instances for UVec3/Vec3/Vec4.

0.2.6.0

• Geomancy.Gl.Block extract to gl-block package as Graphics.Gl.Block.
• Added convert function to vector modules to facilitate type-changing operations like rounding.
• Added Ix instances for integral vectors.
• Added dot for integral vectors.

0.2.5.0

• Added Geomancy.Gl.Block to derive packed/std140/std430 layouts generically. Originally a part of the unpublished glow package in the codex project by Edward Kmett. Add ptrdiff-0 to your stack resolvers.

0.2.4.2

• Support ARM/aarch64 SIMD.

0.2.4.1

• Support simple-affine-space-0.2

0.2.4.0

A bunch of experimental code to see what sticks.

• Added simple-affine-space instances.
  • The classes are re-exported from Geomancy, bringing stuff like dot and normalize.
• Added mono-traversable instances and Geomancy.Elementwise wrapper.
• Added Point wrapper and PointN aliases.
• Added Geomancy.Interpolate with generic linear, quadratic and cubic functions.
  • ⚠️ VecN.lerp has wrong (flipped) order of vector arguments. This is fixed in linear.
• Added Geomancy.Swizzle overloaded labels.
• Added Geomancy.Gl.Funs with kinda-GLSL math functions, appropriately overloaded.
