This is because nearly all rectangles currently depend on previously rendered contents for correct transparency, and lines are so rarely used that it's not worth optimising them. Rectangles and lines are added to the command buffers, but are currently still processed as individual draw calls. As many atlases are created as needed when new textures come in, and the system can scale up to 2048 atlases simultaneously on most implementations. The bottom-right coordinates are based on the actual size of the image and not the entire power-of-two block. Once a texture is in an atlas like that, the draw command only needs 2 parameters to access the texture: the index of the atlas and the top-left to bottom-right coordinates within the atlas. Here are two examples of what atlases look like in the array texture (from RenderDoc): The idea of having different atlases for different power-of-two size textures is to ensure tight packing to waste as little VRAM as possible. The square regions are always equal to the power-of-two size that the atlas was created for. Each texture image is assigned a single square region in the appropriate atlas. All of the atlases have the same dimensions (required for texture arrays), but the images within do not.

If a new texture comes in and there is no suitable texture atlas with any free spots left, then a new atlas is created and added to the array texture of atlases. Texture atlases are created for a specific power-of-two texture size like 32x32, 64圆4 and so on. Instead, the implementation uses a collection of texture atlases. Iterating over all of them would be bad for performance. It was proposed to use multiple samplers in combination with multiple arrays, but unfortunately GLSL does not allow selecting a sampler using a dynamic index. Given that some frames contain over 10k+ sprites with many unique textures, this is simply not scalable enough. Pure array textures were quickly dismissed, because those too are limited to only 2048 elements on most implementations. The OpenGL renderer in OpenRCT2 uses a hybrid approach: an array texture of atlases. There are two possible approaches to expose many textures to the shader at once: array textures and texture atlases. Most OpenGL implementations only allow up to 32 texture samplers in a single shader, which is way too limited. To be able to execute many draw commands that access textures in one draw call, they all need to be accessible from the fragment shader simultaneously. The parameters are derived directly from the OpenGL implementation before it was optimized. There are three possible draw calls and their parameters are defined in structs that can be found in the src/drawing/engines/opengl/DrawCommands.h file. Command buffersĭraw commands are queued in so-called command buffers, named after the constructs in the OpenGL GL_NV_command_list extension and Vulkan API. Flushing here means that they are actually sent to the GPU to be processed. Once an operation is executed that depends on previously drawn contents in one way or another, like the post-processing pass or presentation to the screen, the draw operations that are still in the queue are flushed. The parameters include details like bounds, texture, and tertiary colour. To that effort, all of the draw calls in a single frame are not executed immediately, but added to a queue with their parameters. This is necessary to minimise the overhead of CPU -> GPU communication and state changes on the graphics card. It's due to a bug where nested actions don't report the player performing it.The OpenGL renderer implementation is based around the idea of batching as many drawing operations as possible into a single draw call for the graphics card.
Track designs cause problems with ffa-ownership and ffa-individual-economy, so this plugin prevents them from being built in the first place. Prevents the construction of prefabricated track layouts. Money is earned from the rides that they build. ffa-individual-economyĮach player has their own funds that they use for building. Toggles 4 cheats on launch (disable vandilism, plants don't age, disable all breakdowns, and ride value doesn't decrease), and keeps grass clear. Watch as they try to reconnect but to no avail! The default ban time is 60 minutes but can be adjusted in via ip-ban.timeout. Set a player's group to IP-BAN and they will be kicked and blocked from reconecting until the ban expires. Kicks players for performing too many griefy actions too quickly. Currently only prevents opening a ride with no path connected to its exit. Players cannot make any changes to rides that they didn't make. Free for all plugin suite for OpenRCT2 multiplayer.
