2017-04-26sparkler: add virtual flag to particle_props_tVito Caputo
The burst particle abused a zero mass to circumvent the effects of aging. Instead use an explicit virtual flag to suppress aging, change busrt_cb to ignore all virtual particles instead of only its center. Previously burst_cb would thrust other bursts like any other particle, and this was incorrect. Now burst centers are always stationary, even when they overlap other bursts.
2017-04-22*: add module context machineryVito Caputo
introduces create_context() and destroy_context() methods, and adds a 'void *context' first parameter to the module methods. If a module doesn't supply create_context() then NULL is simply passed around as the context, so trivial modules can continue to only implement render_fragment(). A subsequent commit will update the modules to encapsulate their global state in module-specific contexts.
2017-04-22*: /render/render_fragment/ in rototiller_module_tVito Caputo
Adding more context to the name in anticipation of adding a prepare_frame() method to the module struct.
2017-04-21*: s/renderer/module/gVito Caputo
Make consistent with the source directory structure naming.
2017-04-21sparkler: remove vestigial draw.h from Makefile.amVito Caputo
2017-02-03*: use fb_fragment_zero() instead of memset()Vito Caputo
2017-02-03sparkler: drop draw.hVito Caputo
2017-02-03sparkler: use fb.h put_pixel helpersVito Caputo
discards draw_pixel(), introduces helpers.h and a convenience function for bounds checking and oob extermination. Move makergb to helpers.h, draw.h gets removed in a later commit.
2017-02-03rototiller: extricate draw_pixel() bounds checkingVito Caputo
If a z-buffer is added these checks will need to be done independent from and prior to drawing. Also it's silly to makergb() pixels which can't be drawn.
2017-01-18autotools: s#../../#@top_srcdir@/src#Vito Caputo
The relative path broke out-of-tree builds. Previously the following: $ mkdir /tmp/foo $ cd /tmp/foo $ ~/src/rototiller/configure $ make Would fail to compile unable to locate the headers in ~/rototiller/src This fixes it.
2017-01-18*: move source into src/ subdirVito Caputo
Restoring some organizational sanity since adopting autotools.
