Update animated parameters by getting current time from renderer #234

usakhelo · 2018-10-14T05:01:24Z

Hi,
This PR fixes bug #212. OSL materials and textures were not updated during animation rendering. Now they are working. What I did is instead of getting current with the call GetCOREInterface()->GetTime() I added a function to renderer to get currently rendered frame from the it.

Thanks for review!
Sergo.

Use TimeValue out of consistency with the rest of the code.

 // appleseed-max headers.
 #include "appleseedoslplugin/osltexture.h"
+#include "appleseedrenderer/appleseedrenderer.h"


I find it a bit concerning that utilities depends on appleseedrenderer: lower level components should never depend on higher level ones. Maybe get_current_time() should be declared in appleseedrenderer.{h,cpp}.

For the same reason I'm slightly concerned about the dependencies toward appleseedoslplugin/osltexture.h and osloutputselectormap/osloutputselector.h.

Can I make get_current_time in appleseedrenderer a global function, not the class member? So that I don't have to check and cast current renderer to get the time.

Yes, that's what I meant. You could also make it a static method of AppleseedRenderer to highlight the dependency to that class.

I'm trying to move it to the renderer class but in some utilities I still need to call that function so I still need to include renderer header.

Other way is to pass time from the renderer to all that create_material and so on as an argument.

usakhelo · 2018-10-15T00:32:41Z

Hi @dictoon ,
I added time parameter to the utility functions and then I noticed that only couple of other functions need to be changed in order to get rid of static get_time function. So I decided to change all the functions and now time is passed from the project builder to each material creation function.
It may seem too much of parameters to some of the functions, but it also makes it obvious that they all need time information to work correctly.

luisbarrancos · 2018-10-15T02:44:43Z

This might be relevant:
AcademySoftwareFoundation/OpenShadingLanguage#828
OSL will have acess to global (or camera) frame.

dictoon · 2018-10-15T20:48:10Z

So I decided to change all the functions and now time is passed from the project builder to each material creation function.

In my opinion, definitely the right solution as it makes dependencies clear.

Looking good! Feel free to merge after you've addressed the few remaining details I reported.

explicit has become redundant here, not that it really hurts...

Make time const.

Can it be made const here too? (I think so.)
