-Blender Buildbot
-================
-
-Code signing
------------
-
-Code signing is done as part of INSTALL target, which makes it possible to sign
-files which are aimed into a bundle and coming from a non-signed source (such as
-libraries SVN).
-
-This is achieved by specifying `worker_codesign.cmake` as a post-install script
-run by CMake. This CMake script simply involves an utility script written in
-Python which takes care of an actual signing.
-
-### Configuration
-
-Client configuration doesn't need anything special, other than variable
-`SHARED_STORAGE_DIR` pointing to a location which is watched by a server.
-This is done in `config_builder.py` file and is stored in Git (which makes it
-possible to have almost zero-configuration buildbot machines).
-
-Server configuration requires copying `config_server_template.py` under the
-name of `config_server.py` and tweaking values, which are platform-specific.
-
-#### Windows configuration
-
-There are two things which are needed on Windows in order to have code signing
-to work:
-
- `TIMESTAMP_AUTHORITY_URL` which is most likely set http://timestamp.digicert.com
- `CERTIFICATE_FILEPATH` which is a full file path to a PKCS #12 key (.pfx).
-
-## Tips
-
-### Self-signed certificate on Windows
-
-It is easiest to test configuration using self-signed certificate.
-
-The certificate manipulation utilities are coming with Windows SDK.
-Unfortunately, they are not added to PATH. Here is an example of how to make
-sure they are easily available:
-
-```
-set PATH=C:\Program Files (x86)\Windows Kits\10\App Certification Kit;%PATH%
-set PATH=C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64;%PATH%
-```
-
-Generate CA:
-
-```
-makecert -r -pe -n "CN=Blender Test CA" -ss CA -sr CurrentUser -a sha256 ^
-         -cy authority -sky signature -sv BlenderTestCA.pvk BlenderTestCA.cer
-```
-
-Import the generated CA:
-
-```
-certutil -user -addstore Root BlenderTestCA.cer
-```
-
-Create self-signed certificate and pack it into PKCS #12:
-
-```
-makecert -pe -n "CN=Blender Test SPC" -a sha256 -cy end ^
-         -sky signature ^
-         -ic BlenderTestCA.cer -iv BlenderTestCA.pvk ^
-         -sv BlenderTestSPC.pvk BlenderTestSPC.cer
-
-pvk2pfx -pvk BlenderTestSPC.pvk -spc BlenderTestSPC.cer -pfx BlenderTestSPC.pfx
-```

Clément Foucault	b063115d4e	EEVEE: Remove softness parameters from RNA & UI Keep it in DNA for backward compatibility	2019-09-02 16:41:07 +02:00
Clément Foucault	312dbf8af1	EEVEE: Fix sunlight when sun angle is 180 degrees	2019-09-02 16:41:07 +02:00
Clément Foucault	eb8093cb14	EEVEE: Shadow: Add back shadow bias This is needed in some corner case (shadow acne due to aliasing and depth disparity). This is a simple bias added to default bias. It should not be needed most of the time but we leave it at 1 by default.	2019-09-02 16:41:07 +02:00
Clément Foucault	6adaa4202a	EEVEE: Fix spotlight shadow optimization Spot light can be non-uniform and scale in one direction. This fix makes sure both directions are taken into account before skipping cubemap faces.	2019-09-02 16:41:07 +02:00
Clément Foucault	4dd3a9790f	UI: Make cascaded shadowmap panel on top of contact shadow This make more sense as cascade parameters are more important.	2019-09-02 16:41:07 +02:00
Clément Foucault	c584116e25	EEVEE: Shadow: Add temporal sampling to shadowmaps If soft shadows is enabled, we randomize the shadowmap sample position to reduce aliasing artifacts (jagged edge shadows).	2019-09-02 16:41:07 +02:00
Clément Foucault	3e10785c60	Cleanup: EEVEE: Split eevee_lights.c into smaller files Also have some const correctness fix and some header cleanup.	2019-09-02 16:41:07 +02:00
Clément Foucault	9468425524	Eevee: Shadow: Refactor / Cleanup of shadow update - Replace EEVEE_lightbits by BLI_bitmap - Replace EEVEE_BoundSphere by BoundSphere - Support for dupli light shadows - Detect unecessary update of soft shadows (i.e: moving the view) - Remove Object references	2019-09-02 16:41:07 +02:00
Clément Foucault	31e21d38e3	Eevee: Light: Refactor shadow tagging to allow dupli shadow casters Dupli objects can now cast shadows. This also replace the custom lightbits by BLI_bitmap.	2019-09-02 16:41:07 +02:00
Clément Foucault	8457593672	Eevee: Shadows: Add texel border on shadow cube for better edge filtering Unfortunately, this seems to be imprecise on lower cube resolution. But the result is still most of the time more pleasant than no border filtering.	2019-09-02 16:41:06 +02:00
Clément Foucault	e13f5cc5ae	Eevee: Shadow: Speedup: Only render shadow cube face needed This reduce the number of face to render to 5 in the case of area lights and 5 or 1 for spotlights. Spotlights that have a spot size less than 90 degrees only need 1 face and are the fastest.	2019-09-02 16:41:06 +02:00
Clément Foucault	278d174e35	Eevee: Shadows: Make shadowmap follow light orientation This is in preparation of an optimization	2019-09-02 16:41:06 +02:00
Clément Foucault	d5555e5d5a	DRW: Add line offset to DRW_STATE_SHADOW_OFFSET This is needed for hairs.	2019-09-02 16:41:06 +02:00
Clément Foucault	585eaa5b0a	Eevee: Shadows: Improve contact shadows Contact shadows now follow the shadowmap direction. This means it matches the shadowmap blur that is proportional to the light radius. Moreover this adds a more efficient bias for most contact shadows.	2019-09-02 16:41:06 +02:00
Clément Foucault	4ec63b5421	Eevee: Shadow: Speedup: Use only 2 sample for cascaded shadowmap	2019-09-02 16:41:06 +02:00
Clément Foucault	a77301289d	Eevee: Shadow: Remove receiver plane bias and use hardware filtering In an attempt to simplify the shadowing in eevee, we remove the bias and filtering option. Now the shadowmap always get the minimum constant and slope bias and we only do a bilinear shadow filtering. This means the shadow is as sharper and exact as the shadow map format allows (bitdepth and size). Only the lamp size can change the shadow softness.	2019-09-02 16:41:06 +02:00
Clément Foucault	95a3c256dc	Eevee: Shadow: Make sun clip distances automatic This simplify sun lights setup and matches more cycles behavior.	2019-09-02 16:41:06 +02:00
Clément Foucault	0edd48c904	Eevee: Remove ESM and VSM code	2019-09-02 16:41:06 +02:00
Clément Foucault	9e19ec0d18	Eevee: Shadows: Add Receiver Plane Depth Bias This bias replace the previous bias method. The bias is now scalled to have the correct depth of the triangle at the sample location. This is done by computing the actual depth that would be recorded in the shadowmap at the texels locations, if the triangle was extrapolated. This leads to less shadow acne and it ensure the bias is always the minimum amount that ensure correct shadowing. However this technique is not failure free and if the receiver is nearly parallel to the light, the bias is nearly infinite and light leaking occurs. For this reason I decided to cap the bias by the bias parameter to tweak between shadow acne and light leaking.	2019-09-02 16:41:06 +02:00
Clément Foucault	e951f5f0fe	Eevee: Replace ESM and VSM by PCF shadow mapping PCF shadowmaps are less prone to light leaking and are faster to render. This remove a substantial part of the shadowing code.	2019-09-02 16:41:06 +02:00
Clément Foucault	4df76629a5	DRW: Add shadow bias state This state add shadowmap bias to avoid most of self shadowing.	2019-09-02 16:41:06 +02:00
Clément Foucault	786b0c6414	Eevee: SSS: Refactor translucency This separate the translucency evaluation to be outside of surface eval. This as the benefit to reduce code complexity and remove the need for shadow map (non-test) sampler in the shading pass. One big change is that bsdf intensity is multiplied and stored with the albedo color instead of the sss irradiance. This is in order to apply it to both the translucency and the sss diffusion. This change the look of mixed SSS shaders which is now closer to cycles. Performance cost is negligeable. # Conflicts: # source/blender/gpu/shaders/gpu_shader_material.glsl	2019-09-02 16:41:02 +02:00
Clément Foucault	9ee5e73a3d	Eevee: SSS: Refactor to use less memory and always use separate albedo This refactor reduce the Memory overhead of SSS and enables us to always use separate albedo. Previously we used 128bits/px for SSS data and 32bits/px for albedo. Now we use 112bits/px for SSS data & separate albedo altogether. This refactor is needed for PCF shadow maps. # Conflicts: # source/blender/gpu/shaders/gpu_shader_material.glsl	2019-09-02 16:38:14 +02:00
