285947318f Fix for OSL closure base class. The 'blur' method is not implemented and must be declared pure virtual ('= 0') to avoid compiler error (on Ubuntu 12.04, gcc 4.6.3). 2012-10-21 09:10:47 +00:00

d36dc6d8de Integer socket support in Cycles. Int values are already supported natively in OSL, but were not used as actual ints on the SVM stack. This patch implements all the necessary functionality to support reading input values from RNA properties and convert between SHADER_SOCKET_INT and other types. 2012-10-20 13:11:45 +00:00

9a1c1f132d Cycles OSL: most closure code is now shared between OSL and SVM. Also fix
transmission pass and filter glossy option.

The BSDF closure class is now more similar to the SVM closures, and includes
some flags and labels that are needed to properly categorize the BSDF's for
render passes. Phong closure is gone for the moment, needs to be adapated to
the new structure still.

3abef3a2e6 Cycles OSL: some build system tweaks to avoid global includes and definitions,
which ensures there is no conflict with other libraries, and avoids full rebuild

9f8070d047 code cleanup:
- define array sizes for functions that take vectors.
- quiet some -Wshadow warnings.
- some copy/paste error in readfile.c made it set the same particle recalc flag twice.

d396bf3546 Fix for OSL compile errors.
1) object_fetch_transform_motion omits the per-object motion blur test (r51394), must use object_fetch_transform_motion_test.
2) KernelCamera.ndctoworld has been removed (r51402), do transform invert directly.

tangents from generated coordinates are computed per pixel on the fly, avoids
bad interpolation of singularities.

6915394a3b Attempts to fix CUDA issues on sm 2.0 cards, still no luck getting motion blur
working, but this should make it not crash.

Also fix for wrong shutter time, should have been shorter.

d08b06f773 Cycles: motion blur is now curved and passes exactly through the midpoint.
Previously it would only interpolate between the previous and next frame,
which meant it might not hit the current frame position.

0551aa14bb Fix for OSL 'background' attributes (attributes that are not associated to a particular object). Atm this is only the 'ray_length' attribute.
Background attributes are used as fallback in two cases:
1) Non-object light samples (e.g. lamp shaders)
2) Fallback if no implicit object attribute can be found

536d9fec80 code cleanup:
- move object_iterators.c --> view3d_iterators. (ED_object.h had to include ED_view3d.h which isn't so nice)
- move projection functions from view3d_view.c --> view3d_project.c (view3d_view was becoming a mishmash of utility functions and operators).
- some some cmake includes as system-includes.

af537c283c Fix for (camera) motion blur changes in Cycles OSL. Compilation was broken due to changed object transform functions. Also added a few missing renderer service implementations for matrix callbacks. 2012-10-16 10:59:35 +00:00

7521ce083d Cycles: object motion blur enabled, so in addition to camera motion, moving
objects in the scene will also cause motion blur.

This change does come with a bit of a slow down to the CPU rendering kernel even
with motion blur disabled, due to extra overhead in handling of object matrices.
It's a few percentages on simpler scenes, not so noticeable on more complex ones.
With motion blur enabled rendering is of course also slower as would be expected,
though from testing especially GPU rendering handles it quite well.

This does not support motion blur from deforming objects yet, only translation,
scale and rotation. Deformation blur is probably for another release.

fe09b24e86 Cycles: per-BSDF normal input and new Bump node.
Each BSDF node now has a Normal input, which can be used to set a custom normal
for the BSDF, for example if you want to have only bump on one of the layers in
a multilayer material.

The Bump node can be used to generate a normal from a scalar value, the same as
what happens when you connect a scalar value to the displacement output.

Documentation has been updated with the latest changes:
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes

Patch by Agustin Benavidez, some implementation tweaks by me.

f0a9b66469 Cycles: Anisotropic BSDF enabled, with tangents now computed from the active UV map.
It's using the Ward BSDF currently, which has some energy loss so might be a bit
dark. More/better BSDF options can be implemented later.

Patch by Mike Farnsworth, some modifications by me. Currently it's not possible yet
to set a custom tangent, that will follow as part of per-bsdf normals patch.

78978dcd80 Fix for a case of 'static initialization fiasco' with OSL closure variables. The parameter lists are using OIIO::TypeDesc static standards, which are also static variables. With static OSL libraries these are not initialized when the closure parameter lists are initialized, so OSL rejects the closure types.
Putting static initialization into functions works just as well, but ensures the OIIO::TypeDesc access is delayed until initialization is complete.

fedc8e1722 Cycles: add "From Dupli" option for texture coordinate node. This gets the
Generated and UV coordinates from the duplicator of instance instead of the
object itself.

This was used in e.g. Big Buck Bunny for texturing instanced feathers with
a UV map on the bird. Many files changed, mainly to do some refactoring to
get rid of G.rendering global in duplilist code.

21964e6538 OSL implementation of RGB ramp node.
The sampled color ramp data is passed to OSL as a color array. This has to be done as actual float[3] array though, since the Cycles float3 type actually contains 4 floats, leading to shifting color components in the array.

Additional parameter set functions for arrays have been added to the Cycles OSL interface for this purpose.

c4de45e56b Implemented the Particle Info for OSL. Uses the following attributes:
* std::particle_index
* std::particle_age
* std::particle_lifetime
* std::particle_location
* std::particle_size
* std::particle_velocity
* std::particle_angular_velocity

Just as with SVM the rotation state attribute is currently disabled due to lack of a proper quaternion or matrix type in Cycles nodes.

df79ab5a77 Added Object Info node implementation for OSL. This uses an additional attribute check in the osl_services callback for special attribute names related to objects:
* std::object_location
* std::object_index
* std::material_index
* std::object_random

Other object-based attributes can be added for particle info in the same way.
