For Perspective Texture Mapping you'll need to supply some sort of depth value. This article explains more: https://mtrebi.github.io/2017/03/15/texture-mapping-affine-perspective.html

Magic! But its working)) Thanks a lot!

Graphics / Perspective distortion issue [Solved]

« on: February 15, 2024, 07:06:29 pm »

Hi all. I'm trying to draw a distorted square to simulate perspective. I use rendering through an array of vertices. And as a result I get a strange picture. I tried using different vertices modes (PrimitiveType.Quads and PrimitiveType.Triangles), the result was the same.
I would be very grateful if anyone could suggest a solution on how to get the correct picture.

Using a single vertex array for the whole map would be a better solution

Thanks a lot!

Graphics / Tiled map draw algorithm

« on: August 18, 2020, 05:13:59 pm »

Hey guys!
I'm new with SFML, can anyone give me a little advice?
I want to draw big tiled map. I'm going to use something like that:

sf::Texture texture;
sf::Sprite sprite;
texture.loadFromFile("tileAtlas.png"); //Big texture with all tiles
...
for (i = 0; i < mapWidth; i++) {
  for (j = 0; j < mapHeight; j++) {
    sprite.setTextureRect(..); //Change sprite to appropriate tile
    sprite.move(...); //Move sprite to position of tile (i,j)
    window.draw(sprite);

Is it good practice? Or better to create big array of sf::Sprite?

And another question: do I need to manually check if sprite is on screen (before draw) when using View? Or I can call "draw" to all my big amount of sprites?
