2020-08-07Code Style: use "#pragma once" in source directoryJacques Lucke
This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`. Differential Revision: https://developer.blender.org/D8466
2020-08-02Particles: new Age Reached Event, Kill Particle and Random Float nodeJacques Lucke
The hardcoded age limit is now gone. The behavior can be implemented with an Age Reached Event and Kill Particle node. Other utility nodes to handle age limits of particles can be added later. Adding an Age Limit attribute to particles on birth will be useful for some effects, e.g. when you want to control the color or size of a particle over its life time. The Random Float node takes a seed currently. Different nodes will produce different values even with the same seed. However, the same node will generate the same random number for the same seed every time. The "Hash" of a particle can be used as seed. Later, we'd want to have more modes in the node to make it more user friendly. Modes could be: Per Particle, Per Time, Per Particle Per Time, Per Node Instance, ... Also a Random Vector node will be useful, as it currently has to be build using three Random Float nodes.
2020-07-21Particles: initial object socket and emitter node supportJacques Lucke
Object sockets work now, but only the new Object Transforms and the Particle Mesh Emitter node use it. The emitter does not actually use the mesh surface yet. Instead, new particles are just emitted around the origin of the object. Internally, handles to object data blocks are passed around in the network, instead of raw object pointers. Using handles has a couple of benefits: * The caller of the function has control over which handles can be resolved and therefore limit access to specific data. The set of data blocks that is accessed by a node tree should be known statically. This is necessary for a proper integration with the dependency graph. * When the pointer to an object changes (e.g. after restarting Blender), all handles are still valid. * When an object is deleted, the handle is invalidated without causing crashes. * The handle is just an integer that can be stored per particle and can be cached easily. The mapping between handles and their corresponding data blocks is stored in the Simulation data block.
2020-07-17Nodes: move some code from blenkernel directory to nodesJacques Lucke
This also introduces the `blender::nodes` namespace. Eventually, we want to move most/all of the node implementation files into this namespace. The reason for this file-move is that the code fits much better into the `nodes` directory than in the `blenkernel` directory.
2020-07-07Nodes: Generate multi-function network from node treeJacques Lucke
This adds new callbacks to `bNodeSocketType` and `bNodeType`. Those are used to generate a multi-function network from a node tree. Later, this network is evaluated on e.g. particle data. Reviewers: brecht Differential Revision: https://developer.blender.org/D8169
2020-06-28Use const in nodeFindSocketAnkit
Since the function only iterates over the input members, and matches their identifiers, `bNode *`can be `const`. All other usages of the `nodeFindSocket` use it with other functions that modify the node. (e.g.: ``nodeAddLink` ) But an exporter needs the node to be a `const`, so this creates unnecessary and slightly unsafe design changes.

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
2020-04-20Simulations: Embed simulation node tree in simulation data blockJacques Lucke
This adds an embedded node tree to the simulation data block dna. The UI in the `Simulation Editor` has been updated to show a list of simulation data blocks, instead of individual node trees. The new `SpaceNodeEditor.simulation` property wraps the existing `SpaceNodeEditor.id` property. It allows scripts to get and set the simulation data block that is being edited.

2020-04-03Cleanup: Rename ExtensionRNA variables from ext to rna_extJulian Eisel
Makes it more clear that code using this is related to the RNA integration of a type. Part of T74432. Also ran clang-format on affected files.
2020-03-17Cleanup: Fix warnings about function signature of register passRay Molenkamp
RE_engine_register_pass is sometimes in the headers with type as an integer parameter, sometimes as eNodeSocketDatatype. This caused warnings, the root cause was makesrna was not able to generate the proper type for enums and defaulted to int. makesrna has been extended with the RNA_def_property_enum_native_type that allows telling makesrna the native type of an enum, if set it will be used otherwise it will still fall back to int.

2020-03-06Cleanup: Rename ARegion variables from ar to regionJulian Eisel
The old convention was easy to confuse with ScrArea. Part of https://developer.blender.org/T74432. This is mostly a batch rename with some manual fixing. Only single word variable names are changed, no prefixed/suffixed names. Brecht van Lommel and Campbell Barton both gave me a green light for this convention change. Also ran clan clang format on affected files.

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

2019-10-10Fix T70614 EEVEE: Bump with texture connected to other branches don't workClément Foucault
Was caused by the bump node not being evaluated because the other branch was evaluated before. To fix this, we use fromnode instead of tonode. Also we fix a potential issue with recursiveness because ntree_shader_copy_branch() also use nodeChainIterBackwards() which would reset the iter_flag in the middle of the parent iteration. Use iter_flag as a bitflag for each iteration to fix this.

2019-08-28Fix T68971: Copy As New Driver from Material node creates a bad reference.Alexander Gavrilov
NodeTree structures of materials and some other data blocks are effectively node group datablock objects that are contained inside the parent block. Thus, direct references to them are only valid while blender is running, and are lost on save. Fix Copy As New Driver to create a reference that goes through the owner datablock, by adding a new ID flag to mark private pseudo-datablocks. Also fix functions that return full paths to structures and properties, e.g. used in python tooltips. Functions for paths from ID to struct or property can't be changed because of Animation Data related code. Reviewers: mont29 Differential Revision: https://developer.blender.org/D5559

2019-08-22Revert "Fix T68971: Copy As New Driver from Material node creates a bad ↵Bastien Montagne
reference." This reverts commits 54fd8176d7e91, 4c5becb6b1 and 8f578150e. Those kind of commits must be reviewed and approved by project owners. That one: * Broke Collada building by not properly updating all calls to modified function. * Broke *whole* ID management by not properly updating library_query.c. And in general, I am strongly against backward ID pointers, those are *always* a serious PITA for ID management. Sometimes they cannot be avoided, but in general other ways to get that kind of info should be investigated first.
