2020-05-15Fix T76277: Remove wrong cast in rna_NodeTree_updateRobert Guetzkow
This patch fixes T76277 by removing the incorrect cast from `ptr->data` to `bNode`. The address of `ptr->owner_id` and `ptr->data` both point to the node tree. Passing the node tree incorrectly as a node into the `ED_node_tag_update_nodetree` corrupts the data, because it attempts to set flags on the node.

2020-04-20Simulations: UI for core particle nodesJacques Lucke
This commit adds the initial set of particles nodes. These are fairly low level and are expected to be put into groups that we ship with Blender. See D7384 for a description of the individual nodes. Reviewers: brecht Differential Revision: https://developer.blender.org/D7384
2020-04-20Nodes: Add emitters, events, forces and control flow socket typesJacques Lucke
These socket types will be necessary for particle nodes. The way these sockets are drawn can be changed separately. Reviewers: brecht Differential Revision: https://developer.blender.org/D7349
2020-04-20Nodes: New Object and Image socket typesJacques Lucke
Those new socket types will be necessary for particle nodes. The main difficulty with adding these socket types is that they are the first that reference ID data in their `value`. Therefore, user counting code had to be added in a couple new places. Reviewers: brecht, mont29 Differential Revision: https://developer.blender.org/D7347
2020-04-20Simulations: Add simulation node tree typeJacques Lucke
This implements a new builtin node tree type called `SimulationNodeTree`. It is not yet embedded in the `Simulation` data block. The node tree will initially be used for the new particle nodes system. When the cmake option `WITH_NEW_SIMULATION_TYPE` is enabled, a new `Simulation Editor` is shown in the editors menu (which is just a node editor). This patch does not add entries to the Add Node menu, so it is empty. Reviewers: brecht Differential Revision: https://developer.blender.org/D7287

2020-03-06Nodes: Support storing socket link limits in bNodeSocketTypeJacques Lucke
Currently the link limit of sockets is stored in bNodeSocket->limit. This allows for a lot of flexibility, but is also very redundant. In every case I've had to deal with so far, it would have "more correct" to set the link limit per socket type and not per socket. I did not enforce this constraint yet, because the link limit is exposed in the Python API, which I did not want to break here. In the future it might even make sense to only support only three kinds of link limits: a) no links, b) at most one link, c) an arbitrary number links links. The other link limits usually don't work well with tools (e.g. which link should be removed when a new one is connected?) and is not used in practice. However, that is for another day. Eventually, I would like to get rid of bNodeSocket->limit completely and replace it either with fixed link limits or a callback in bNodeSocketType. This patch consists of three parts: **1. Support defining link limit in socket type** This introduces a new `nodeSocketLinkLimit` function that serves as an indirection to hide where the link limit of a socket is defined. **2. Define link limits for builtin sockets on socket type** Data sockets: one input, many outputs Virtual sockets: one input, one output Undefined sockets: many inputs, many outputs (to avoid that links are removed when the type of the socket is not known) **3. Remove `bNodeSocketTemplate->limit`** This wasn't used anymore after the second commit. Removing it simplifies socket definitions in hundreds of places and removes a lot of redundancy.

2019-12-10Cycles: support for custom shader AOVsLukas Stockner
Custom render passes are added in the Shader AOVs panel in the view layer settings, with a name and data type. In shader nodes, an AOV Output node is then used to output either a value or color to the pass. Arbitrary names can be used for these passes, as long as they don't conflict with built-in passes that are enabled. The AOV Output node can be used in both material and world shader nodes. Implemented by Lukas, with tweaks by Brecht. Differential Revision: https://developer.blender.org/D4837
2019-12-07Shader Nodes: Add Interpolation modes to Map Range nodeCharlie Jolly
Modes: Linear interpolation (default), stepped linear, smoothstep and smootherstep. This also includes an additional option for the **Clamp node** to switch between **Min Max** (default) and **Range** mode. This was needed to allow clamping when **To Max** is less than **To Min**.

2019-12-07Maths Node: Additional functionsCharlie Jolly
When creating shaders and using maths functions it is expected that Blender should match functions in other DCC applications, game engines and shading languages such as GLSL and OSL. This patch adds missing functions to the Blender maths node. Ideally, it would be nice to have these functions available to vectors too but that is not part of this patch. This patch adds the following functions trunc, snap, wrap, compare, pingpong, sign, radians, degrees, cosh, sinh, tanh, exp, smoothmin and inversesqrt. Sign function is based on GLSL and OSL functions and returns zero when x == 0. Differential Revision: https://developer.blender.org/D5957

2019-09-12Shading: Add More Features To The Voronoi Node.OmarSquircleArt
This patch allows the Voronoi node to operate in 1D, 2D, and 4D space. It also adds a Randomness input to control the randomness of the texture. Additionally, it adds three new modes of operation: - Smooth F1: A smooth version of F1 Voronoi with no discontinuities. - Distance To Edge: Returns the distance to the edges of the cells. - N-Sphere Radius: Returns the radius of the n-sphere inscribed in the cells. In other words, it is half the distance between the closest feature point and the feature point closest to it. And it removes the following three modes of operation: - F3. - F4. - Cracks. The Distance metric is now called Euclidean, and it computes the actual euclidean distance as opposed to the old method of computing the squared euclidean distance. This breaks backward compatibility in many ways, including the base case. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5743

2019-09-05Shading: Rewrite Mapping node with dynamic inputs.OmarSquircleArt
This patch rewrites the Mapping node to support dynamic inputs. The Max and Min options have been removed. They can be added as Min and Max Vector Math nodes manually. Texture nodes still use the old matrix-based mapping. A new SVM node `NODE_TEXTURE_MAPPING` has been added to preserve this functionality. Similarly, in GLSL, a `mapping_mat4` function has been added. Reviewers: brecht, JacquesLucke
2019-09-04Shading: Extend Noise node to other dimenstions.OmarSquircleArt
This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D space. The noise code has also been refactored to be more readable. The Color output and distortion patterns changed, so this patch breaks backward compatibility. This is due to the fact that we now use random offsets as noise seeds, as opposed to swizzling and constants offsets.

The old layout of `PointerRNA` was confusing for historic reasons: ``` typedef struct PointerRNA { struct { void *data; } id; struct StructRNA *type; void *data; } PointerRNA; ``` This patch updates it to: ``` typedef struct PointerRNA { struct ID *owner_id; struct StructRNA *type; void *data; } PointerRNA; ``` Throughout the code base `id.data` was replaced with `owner_id`. Furthermore, many explicit pointer type casts were added which were implicit before. Some type casts to `ID *` were removed.

2019-08-22Nodes: Support for socket shapes other than circleCharlie Jolly
Previously there was already "draw_shape" property, but it was doing nothing. This commit renames the property to "display_shape". Furthermore, different shapes like SQUARE and DIAMOND are supported now. Currently, the shapes are drawn using the shader that also draws keyframes. In the future we might want to separate this. The new shapes are not used anywhere yet, but they can be used by addon developers and will probably be useful when we want to support different kinds node systems later. For example, different shapes can be used to distinguish between data and control flow. Differential Revision: https://developer.blender.org/D2829
