* examples: triangle: Simplify by removing projection matrix.David Thompson2023-11-081-6/+5

* First pass of rendering engine rewrite.David Thompson2023-11-086-12/+104
| | | | | | | | The (chickadee graphics gpu) module now handles most of the low-level OpenGL object creation/deletion/binding. The (chickadee graphics engine) module handles the with-graphics-state stuff via a render context object. There's lots of stuff that isn't great, but it's the first step towards a graphics backend agnostic rendering layer.

* render: sprite: Rewrite sprite batching API.David Thompson2019-05-121-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | This new version performs better and has a better API. It closely resembles Love2D's sprite batch API. * chickadee/render/sprite.scm (with-batched-sprites, sprite-batch-reset!, sprite-batch-begin!, draw-sprite-batched, *batch?*, %batch): Delete. (draw-sprite-unbatched): Rename to 'draw-sprite*'. (<sprite-batch>)[index-buffer, position-buffer, texture-buffer]: Delete fields. [vertex-buffer]: New field. (init-sprite-batch, double-sprite-batch-size!, sprite-batch-add!, sprite-batch-flush!): Rewrite. (make-sprite-batch): Add 'capacity' and 'blend-mode' arguments. (draw-sprite-batch): New procedure. (draw-nine-patch*): Stop using sprite batches for now. * chickadee/render/font.scm: (<font>)[sprite-batches]: New field. (load-tile-font, load-font): Create a sprite batch for each texture loaded. (draw-text*): Use sprite batches. * chickadee/render/tiled.scm: (<tile>)[batch]: New field. (<tileset>)[batch]: New field. (load-tile-map): Create a sprite batch for each tileset. (draw-tile-layer): Use new sprite batch API. (draw-tile-map*): Remove reference to deleted macro.

* Re-hide SDL2 details.David Thompson2018-12-136-22/+17
| | | | | | | | | | | | | | | | | | | | | I know I'm backpedaling here, but I think it was a mistake to expose SDL2 as much as I have here. I think it's better for people just getting started to not have to wonder what SDL means. Making things as usable as possible for beginners is an important goal, and abstracting SDL2 + OpenGL things from the core game loop implementation shouldn't require sacrificing that goal. * chickadee.scm: Switch code with... * chickadee/game-loop.scm: ...this! Which is copied straight from... * chickadee/sdl.scm: ...this! Which is now deleted. * Makefile.am (SOURCES): Add game-loop.scm, remove sdl.scm. * examples/grid.scm: Update due to API breakage. * examples/lines.scm: Ditto. * examples/nine-patch.scm: Ditto. * examples/sprite.scm: Ditto. * examples/text.scm: Ditto. * examples/tiled.scm: Ditto. * doc/api.texi (Kernel): Update.
