GPT gave me this, which seems to work when I ran it: public void DrawSphere(int centerX, int centerY, int radius, double angle) { for (int y = -radius; y <= radius; y++) { for (int x = -radius; x <= radius; x++) { if (x * x + y * y <= radius * radius) { double z = Math.Sqrt(radius * radius - x * x - y * y); double xRot = x * Math.Cos(angle) - z * Math.Sin(angle); double zRot = x * Math.Sin(angle) + z * Math.Cos(angle); double u = 0.5 + (Math.Atan2(zRot, xRot) / (2 * Math.PI)); double v = 0.5 - (Math.Asin(y / (double)radius) / Math.PI); int textureX = (int)(u * _textureWidth) % _textureWidth; int textureY = (int)(v * _textureHeight) % _textureHeight; Rgba32 color = _texture[textureX, textureY]; SetPixel(centerX + x, centerY + y, color); } } } }
