C++ (Cpp) PlotPixel Examples

Example #1

File: graphics.cpp Project: OasisGallagher/SimpleGraphicEngine

void Graphics::PlotGradientLine(HDC hdc, const Color& cl,
	const Color& cr, float zl, float zr, float ul, float ur, 
	float vl, float vr, float xl, float xr, int y, const Texture& texture) {
	ColorDiff dc = (cr - cl) / (xr - xl);
	float dz = (zr - zl) / (xr - xl);
	float du = (ur - ul) / (xr - xl);
	float dv = (vr - vl) / (xr - xl);

	Color ci = cl;
	float ui = ul, vi = vl;
	float zi = zl;
	for (int xi = (int)floorf(xl); xi < (int)ceilf(xr); ++xi) {
		Color textel = ci;
		if (ui >= 0 && vi >= 0)
			textel *= texture.Rgb(ui / zi, vi / zi);

		PlotPixel(hdc, xi, y, Round2Integer(zl), textel);
