* render: shader: Remove 'attributes' field.David Thompson2015-11-141-32/+26
| | | | | | | | | | | | Attributes are fixed so the field is useless. * sly/render/shader.scm (shader-program-attribute-location): Delete. (<shader-program>): Delete 'attributes' field. (make-shader-program): Remove 'attributes' argument. (load-shader-program): Likewise. Change arguments from positional to keyword. (%default-shader): New variable.

* config: Fix data directory.David Thompson2015-11-125-11/+16
| | | | | | | | | | | | | | | | | | This was all messed up: - 'pkgdatadir' wasn't something that could be substituted via autoconf - I was still using "GUILE_2D" in the data dir env var name Now it's all better and Sly data should be able to be found from the pre-installation environment *and* the installation prefix. * configure.ac (sly_prefix, sly_datadir): New variables. * pre-inst-env.in: Set SLY_DATADIR. * sly/config.scm.in (%pkgdatadir): Delete. (%datadir): New variable. Use SLY_DATADIR env var or the configured datadir. * sly/render/font.scm (load-default-font): Use %datadir. * sly/render/shader.scm (load-default-shader): Likewise.

| | | | * sly/render/camera.scm (3d-camera): New procedure.

* render: Reimplement rendering engine using functional combinators.David Thompson2015-09-2120-427/+797
| | | | | | | | | | | Warning: This is a huge commit. I completely gutted the old scene graph and replaced it with a somewhat monadic rendering combinator module instead. The interface remains purely functional, but replaces the <model> data type with procedures in the rendering monad instead. This opens the door for rendering *anything*, not just meshes. Now I can implement particle systems and other non-static things.
* Add new record type syntax.David Thompson2015-09-212-0/+55
| | | | | * sly/record.scm: New file. * Makefile.am (SOURCES): Add it.
* render: mesh: Tweak with-mesh to use null-mesh.David Thompson2015-09-091-1/+1
| | | | | * sly/render/mesh.scm (with-mesh): Apply the null-mesh after evaluating the body.
* render: mesh: Add custom record type printer.David Thompson2015-09-091-0/+9
| | | | | | | | This avoids an issue where debugging output would be clogged by dumping *all* of the vertex information for large meshes. * sly/render/mesh.scm (<mesh>): Add record type printer that doesn't print out the vertices.
* render: Add separate projection and model-view matrix stacks.David Thompson2015-09-093-35/+49
| | | | | | | | | | | | | | | Just like the Opengl 2.x days! ;) * sly/render.scm (graphics-transform, graphics-transform-mul!, graphics-transform-identity!): Delete. (graphics-model-view-transform, graphics-model-view-mul!, graphics-model-view-identity!, graphics-projection-transform, graphics-projection-mul!, graphics-projection-identity!): New procedures. (with-model-view-excursion, with-projection-excursion): New syntax. (call-with-transform-excursion): Move matrix copying out of the "in guard." (draw-scene): Use new matrix stacks.
* render: Force OpenGL state changes when resetting context.David Thompson2015-09-091-7/+7
| | | | * sly/render.scm (graphics-reset!): Force context changes.
* render: Reset OpenGL state after drawing a frame.David Thompson2015-09-091-1/+4
| | | | | | | | Not resetting the graphics context after rendering leads to strange bugs such as sprites disappearing when a new mesh is created in between drawing. * sly/render.scm (with-graphics): Reset context after drawing.
* render: Reimplement OpenGL state machine manager.David Thompson2015-08-267-238/+243
| | | | | | | | | | | | | The implementation is a bit cleaner, and it's a stepping stone towards render combinators. * sly/render/context.scm: Delete. * sly/render.scm: New file. * Makefile.am (SOURCES): Add it. Remove context.scm. * sly/game.scm (run-game-loop): Use new <graphics> type. * sly/render/model.scm (draw-model): Likewise. * sly/render/scene.scm (draw-scene): Likewise. * examples/2048/2048.scm: Remove (sly render context) import.
* Optimize matrix operations.David Thompson2015-08-253-43/+57
| | | | | | | | | | | | | | | | | | | | | 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.
* Update INSTALL.orgJochem Raat2015-08-051-2/+12
| | | | | | Add the Gnu Scientific Library (GSL) to the dependencies and update the git clone command for sly itself to the new address of the repository (https://git.dthompson.us/sly.git), since gitorious is down.
* Fix Guix development environment.David Thompson2015-08-051-1/+1
| | | | * package.scm: Change source to #f for now.
* examples: Add Conway's Game of Life.Christopher Allan Webber2015-06-152-0/+338
| | | | | * examples/life.scm: New file. * examples/Makefile.am (nobase_dist_examples_DATA): Add it.
* Add composite (sly) module.David Thompson2015-06-146-41/+72
| | | | | | | | | * sly.scm: New file. * Makefile.am (SOURCES): Add it. * sandbox.in: Use new module. * examples/common.scm: Likewise. * examples/font.scm: Likewise. * README ("Example"): Update example.
