The number of rockkville desired frame is calculated based on the time of the video, the number of frames and the current time. Bad Cleaning Practices: Never spray water or Windex or anything like it on the glass itself, when the picture is hanging american art make-a-frame rockville github the wall. Humidity: Humidity is hard on artwork, but even worse when combined with heat.

To do so, we need to import OpenCV library, which is a famous cross-platform computer vision library. The basic idea is to display the generated results one by one, with or without the music. However, the flash during two ASCII images is a big problem, and the synchronization with the sound is another. If we just start playing music and then do some normal display in terminal, there is a high probability that it will be a mess: the video is not fluid at all and the music is misaligned.

I use curses to deal with the refreshing problem. It provides lots of fancy skills to control the terminals: adding text, erasing it, changing its appearance, etc.

My original practice is to display all the results one by one and wait a certain amount of time to achieve the required playback speed. However, it took too much time to read the file and display it.

Therefore, I decided to ignore some frames during playback Another possible solution is to read all files in advance. The number of the desired frame is calculated based on the time of the video, the number of frames and the current time. Instead, for each frame, the number will be calculated precisely.

The code is as follows:. Finally, I broke down and got a second bird feeder, one that was a bit more visible and off the ground. With this, I finally started getting some images like the ones at the beginning of the post.

The code for this post is available at Github , as always. This post is the beginning of a set of lessons where I will use deep learning cameras to try and interact with birds. Finally, feel free to share this post with your friends. It helps me to continue making these sort of tutorials. Building a voice controlled musical game from scratch.

Every frame rendered by a real-time engine is a result of work done both by the CPU and the GPU aka the graphics card. Instead, it has to send the commands using an API: application programming interface. In the case of PC and mobile, these API function calls must be further translated by a graphics driver. An important kind of an API function you should remember is the draw call.

A draw call is a request to draw given meshes precisely: batches of triangles on the screen or into a buffer , using specified shaders. I explain the idea in detail later in this chapter. The goal of the graphics code is to draw what was requested. In an ideal situation, polygons would be transformed, shaded and displayed on the screen. Things are nowhere that simple, though, especially on the PC and mobile.

The commands what to draw — aka the draw calls — are submitted by the engine code. Even the most powerful graphics card can be bottlenecked by an overworked central unit. To make things worse, draw calls before Vulkan and DX12 had to be submitted through the graphics card driver — itself a piece of software, adding another heavy layer of indirection.

For people experienced with object-oriented code, it may be surprising that the classic graphics APIs hold just a single global state of what to render.

To render another mesh or to switch the material means to issue a draw call, changing the globally binded resource. It includes situations like:. All of these would typically require a draw call. A realistic amount of draw calls that a mid-range DXera PC could handle in 16 ms was between hundreds and thousands.

The games usually feature dozens of thousands of meshes in the visible scene. In a physically-based pipeline, each of those meshes probably uses at least 3 textures. Dispatching this many commands would be lethal to performance. To mitigate this issue, programmers have came up with a lot of clever solutions over the years.

The most important is batching , or at least sorting , the requests. The point is to combine the calls if the mesh and all its parameters are identical. A building may consist of thousands of pieces, but probably a lot of those are just instances of the same mesh.

If these meshes were merged into a single object, it would require only 1 draw call.
