This solves an oversight that basically made all atlases share the
their tileSizesFactor, a variable used to quickly lookup tile tile sizes
depending on the shadowMapScale. So if cascade size was higher than cube
map size, then point light atlases would use incorrect values and break.
This is done to make it easier to understand what is going on with
atlases to help users and also the maintenance of the feature.
Max atlas size and max tile size where moved to the graph to make it
more understandable.
* Removed redundant checks at the start of the function.
* changed the return value to void because the "return false" were
redundant, and simply made it so the lightInAtlas is set at the end of
the function.
* Removed unused variable
With this it is now possible to enable atlasing of shadow maps, which solves the existing limitation of 4 lights in a scene. This is done by
grouping the rendering of shadow maps, that currently are drawn into their own images for each light, into one or several big textures. This was
done because the openGL and webGL version Armory targets do not support dynamic indexing of shadowMapSamplers, meaning that the index that
access an array of shadow maps has to be know by the compiler before hand so it can be unrolled into if/else branching. By instead simply
using a big shadow map texture and moving the dynamic part to other types of array that are allowed dynamic indexing like vec4 and mat4, this
limitation was solved.
The premise was simple enough for the shader part, but for the Haxe part, managing and solving where lights shadow maps should go in a shadow map
can be tricky. So to keep track and solve this, ShadowMapAtlas and ShadowMapTile were created. These classes have the minimally required logic
to solve the basic features needed for this problem: defining some kind of abstraction to prevent overlapping of shadowmaps, finding available
space, assigning such space efficiently, locking and freeing this space, etc. This functionality it is used by drawShadowMapAtlas(), which is a
modified version of drawShadowMap().
Shadow map atlases are represented with perfectly balanced 4-ary trees, where each tree of the previous definition represents a "tile" or slice
that results from dividing a square that represents the image into 4 slices or sub-images. The root of this "tile" it's a reference to the
tile-slice, and this tile is divided in 4 slices, and the process is repeated depth-times. If depth is 1, slices are kept at just the initial
4 tiles of max size, which is the default size of the shadow map. #arm_shadowmap_atlas_lod allows controlling if code to support more depth
levels is added or not when compiling.
the tiles that populate atlases tile trees are simply a data structure that contains a reference to the light they are linked to, inner
subtiles in case LOD is enabled, coordinates to where this tile starts in the atlas that go from 0 to Shadow Map Size, and a reference to a
linked tile for LOD. This simple definition allows tiles having a theoretically small memory footprint, but in turn this simplicity might make
some functionality that might be responsibility of tiles (for example knowing if they are overlapping) a responsibility of the ones that
utilizes tiles instead. This decision may complicate maintenance so it is to be revised in future iterations of this feature.
First version:
- Dynamically checking the correctness of an expression in the IDE (Blender).
- The task is divided into 2 parts: checking the correctness through python in the Blender interface and when performing calculations when the application is running in haxe.
The following decisions are taken as a basis:
python - http://repl.it/3xv/1
haxe - https://github.com/maitag/formula (added all the necessary classes to the node code)
1. Move the Quaternion node from Transform to Variable
2. Move the Separate Quaternion node from Transform to Math
3. Added Quaternion Math Node
Linked to PR - https://github.com/armory3d/iron/pull/108
1. Modification of CanvasScript and WasmScript classes: added a field to save the name of the script / file in the class.
2. Added logical nodes for working with Traits.
- Get Object Traits - gets an array of Traits for the specified object;
- Get Trait Name - get the Trait name (the name that appears in the list in Armory Traits) and its type (Canvas, Wasm, Bundle, LogicNode or Haxe).
1. For the new settings to fully function, you need to update the submodules so that this Pull Request (https://github.com/Kode/kincmake/pull/100) gets into armsdk. Extended settings via khafile.js.
2. Added Android Settings panel:
- invisible until the target platform android-hl is added to the list;
- inactive until the target platform android-hl is selected in the list.
Options:
- Orientation;
- Compile Version SDK - from 26 to 30, default 29;
- Minimal Version SDK - from 14 to 30, default 14;
- Target Version SDK - from 26 to 30, default 29;
- Permissions - a list of permissions. If I will duplicate entries in the list, then only unique entries will be included during export. By default, the list is empty;
- Android ABI Filters - a list of platforms to build for (arm64-v8a, armeabi-v7a, x86, x86_64). If I will duplicate entries in the list, then only unique entries will be included during export. By default, the list is empty. If the list is empty, then all platforms will be used (as before).
3. The enum (names of permissions) and the function have been added to the utils.py modules, which adds the specified value to the list of permissions. Feature added for ease of use from different locations (different logical nodes).
4. List of permissions:
- ACCESS_COARSE_LOCATION - Allows an app to access approximate location;
- ACCESS_NETWORK_STATE - Allows applications to access information about networks;
- ACCESS_FINE_LOCATION - Allows an app to access precise location;
- ACCESS_WIFI_STATE - Allows applications to access information about Wi-Fi network;
- BLUETOOTH - Allows applications to connect to paired bluetooth devices;
- BLUETOOTH_ADMIN - Allows applications to discover and pair bluetooth devices;
- CAMERA - Required to be able to access the camera device;
- EXPAND_STATUS_BAR - Allows an application to expand or collapse the status bar;
- FOREGROUND_SERVICE - Allows a regular application to use Service.startForeground;
- GET_ACCOUNTS - Allows access to the list of accounts in the Accounts Service;
- INTERNET - Allows applications to open network sockets';
- READ_EXTERNAL_STORAGE - Allows an application to read from external storage;
- VIBRATE - Allows access to the vibrator;
- WRITE_EXTERNAL_STORAGE - Allows an application to write to external storage.
5. Added logical node Set Vibrate:
Category: Native
Pulses the vibration hardware on the device for time in milliseconds, if such hardware exists.
Input parameters:
- Milliseconds - time in milliseconds (data type Int, default value 100).
When adding the logical node Set Vibrate, the permission is automatically added to the list, even if the target android-hl has not been added to the export list (using a function from utils.py).
