[0.2.0]

Added

  • Cauldron3D.Camera and Cauldron3D.View: perspective and orthographic cameras, with first-person, follow, side-on and top-down set-ups, fitted to a picture and its pixel shape.
  • Cauldron3D.Render, Setup, Raster and Paint: polygons drawn into an indexed-colour Cauldron3D.Frame, each row resolved into runs of the nearest polygon, bands of rows drawn in parallel; flat, textured, light-table, per-vertex shaded, surface, liquid, sky and game-defined paints; see-through and always-on-top polygons.
  • Full colour: Render.draw/3 with :palette draws RGBA frames (Cauldron3D.Paint.Rgba); textures may carry their own palette or be RGBA; surfaces are built from grey or red-green-blue lightmaps (Bsp.light_channels) through a :curve; polygons blend by alpha or add (Polygon.blend); Frame.blit/4 and scale/3 take RGBA frames.
  • :masked texture kind, {:skybox, faces} paint and Bsp.Draw's :skybox option; brush models drawn turned ({model, origin, angles}).
  • Cauldron3D.Mesh (keyframed, blended, lit by normals) and Cauldron3D.Billboard.
  • Cauldron3D.Bsp, Bsp.Face, Bsp.Draw and Bsp.Surfaces: BSP worlds, what a leaf can see, faces drawn with lightmapped surfaces made in parallel and cached per mip level. Bsp.visible_leaves/2 gives world leaves only (Bsp.world_leaves), never a brush model's. Bsp.game names the game a map was made for, :quake or :half_life.
  • Cauldron3D.Bsp.Light, the light under a point, and Bsp.Light.on_face/4, a face's lightmap light at a point on it.
  • Cauldron3D.Quat and Cauldron3D.Skeleton (bone transforms from parent-relative poses).
  • Cauldron3D.Hull (point and box hulls, traces) and Cauldron3D.Move (sliding, stepping).
  • Cauldron3D.Texture, Cauldron3D.Frame (rgba/2, rgb/2, blit/4, scale/3) and Cauldron3D.Vec.
