  • Rendering portal system

    Gaming applications
    Rendering portal system — example of a freelancer's portfolio in the category Gaming applications
    The special engine #rendering created on #Javascript and #WebGL, allows to produce a negative game scene with portals (as in the Portal game), can contain a arbitrary number of portals, portals can connect both the different parts of one scene, and the different dimensions between themselves. It was originally intended to create a browser #games headlock.
  • The 3D game

    Gaming applications
    The 3D game — example of a freelancer's portfolio in the category Gaming applications
    Browser mini #game about the submarine world written on #Javascript with used technology #WebGL. The game is divided into a client and server part (#NodeJS) which allows several players to play on one card. The rendering system is created from scratch, #shadery allows you to qualitatively simulate the water surface. The meaning of the game is similar to many popular io games: you need to eat food and other players of smaller size, grow and thus get to the top.
  • Simulation of fluid

    Data processing
    Simulation of fluid — example of a freelancer's portfolio in the category Data processing
    The algorithm performing numerous solution #equaled Navie-Stock on a square network that allows to get #simulation of fluid flows, has a lot of settings allowing to regulate quality\performance, there is the possibility of installing walls(precautions). Realised on pure JavaScript, #canvas, network 128*128, extremely possible for simulation in real time using JS. This algorithm can be rewrite to C++, in addition to using GPU acceleration to obtain high performance. I can make in #3D, or a similar simulation for a second differential equation, for example, heat conductivity etc.
  • Inercial Tracking System on Arduino

    C and C++
    A small program for the #microcontroller performing the reading of data from the #factor(#accelerometer, #hyroscope), the processing of data and the transmission of ready coordinates and orientations to the PC. A special algorithm performs the filtration of the signal and the depression of the errors using different calibration data including the temperature of the sensor. The data is integrated and the output is quaternion which is transmitted to the PC, where there is a small program that allows to visualize the data. Update frequency approximately 1 to 2 kHz which provides smoothness and fast reaction to small changes in position and orientation of the device. It is possible to transfer data via WiFi or save it on a memory card. It can be used in various projects, as an add-on to optical tracking in VR.

    3D graphics on the microcontroller.

    Embedded systems and microcontrollers
    I was written a small system of rendering 3D images in real time.
    The maximum size of the picture is 256x256 points.
    It allows you to draw both the wire graphics and the painted triangles.
    There is the possibility of imposing texture, pixel and top shadery,
    Z is a buffer, a buffer of trafficate.
    Optimized as much as possible. (for #Arduino Mega2560)
    2 rotating squares give 25fps, the more geometry the less fps.
    Can be improved and used on more powerful controller or to render a quality image not in real time or to create games.
  • Simulator of schemes on logical elements

    Data processing
    Simulator of schemes on logical elements — example of a freelancer's portfolio in the category Data processing
    The browser application allows to easily create small #schems from #logic elements and check their work. A special algorithm can process up to 200 thousand. elements per second and has the experimental mode allowing to perform the simulation in the opposite direction(make values on the output of the scheme or function, get values on the input).

I can't evaluate the project by dignity - because the customer will ignore, from the freelancer - everything is great, done in time!

First the freelancer looked executive, the communication was easy, after a few days it simply disappeared and then said that the project will not be able to perform. I can’t say that somehow has caught me, but I need to be more performing and comply with the promises.
