Salut à tous,
Je conçois en ce moment un système de projection basé sur le Mode 7.
Lorsque je décide d'inclure la librairie <math.h>, j'ai une erreur d'affichage grotesque, il n'y a que la moitié de mon rendu qui s'affiche :
Alors que lorsque je retire "#include <math.h>", tout se redraw parfaitement..
Je ne comprends absolument pas l'erreur.. Voici mon code :
#include <math.h>
#include <iostream>
#include <SFML/Graphics.hpp>
int main()
{
unsigned int WIDTHSCREEN = 800, HEIGHTSCREEN = 600;
sf::RenderWindow app(sf::VideoMode(WIDTHSCREEN, HEIGHTSCREEN), "Rotozoom", sf::Style::Titlebar);
app.setFramerateLimit(60);
sf::RenderWindow render(sf::VideoMode(WIDTHSCREEN, HEIGHTSCREEN), "Render", sf::Style::Titlebar);
render.setFramerateLimit(60);
sf::Clock clock;
std::vector<sf::VertexArray>vecLines;
std::vector<sf::VertexArray>vecQuads;
sf::Vector2f m_position = {100,100};
float angle = 0.0f;
double speedMove = 20;
for (unsigned int i = 0 ; i < HEIGHTSCREEN ; i++)
{
sf::VertexArray line(sf::Lines, WIDTHSCREEN);
for (unsigned int k = 0 ; k < WIDTHSCREEN ; k++)
line[k].position = {0, i};
vecLines.push_back(line);
}
std::vector<std::vector<unsigned int>>vecMap =

Si je retire le "math.h", ça projette sans problème ma perspective, si je l'inclu, la moitié ne s'affiche plus du tout..
Merci à vous !
