perspective drawer

This forum is currently in read-only mode.
  • all this does is draw boxes in 3D!!!!, yea really i wasted my time making this lol. well its not done yet, i plan on adding raytraced lighting and z buffering so its actually usefull, i even plan on making more primitives like triangular prisms and cylinders ,stuff like that.

    it basically works by using 2 point perspective and alot some linear beziers ect ect.

    download and tell me what you think

    i dont know if im going to use it or not, it might be cool to make a game using this, when the lightings implemented

    move the canvas at the top down to see wireframe

  • :O Thats pretty awesome! Sadly if you add textures to those shapes the texture becomes slightly distorted (as opposed to 3d box) because the distortion doesn't allow for texture z distortion. Its on my todo list to look into texture z manipulation because it would be nice if you could distort each corner of a sprite and it mapped the texture in such a way that it looked 3d. But anyways good job! I think I allowed distortion to adjust the filter of each vertex so you could do some kind of vertex lighting if you wanted

  • That's slick

  • Very nice. Looks promising.

    've found that you can correct the texture distortion by having a map size of at least 2x2 (the larger your map size the more correct the texture becomes) and interpolating your X, Y, Z values between points (or just X,Y; I've been emulating my Z value).

    I'm probably not explaining myself very well (I have a habit of doing that). Here is an .exe to show my results however.

    Controls:

    1 = Decrease map size

    2 = Increase map size

    Movement:

    • W,A,S,D
    • Up, Down, Left, Right
    • Ctrl, Space

    Note: The transparency is because it is still very much a work in progress, and as a result lacks a Z Buffer.

  • Ummm that broke my brain just glancing at the events. I'm not even going to pretend I know how that works. Nice job though mate. You guys make me feel super dumb when I look at this kind of stuff.

  • Nice! Seems everyone's in for 3D drawing these days

  • man this thing was hell to program, i forgot about it lol
