Info

Operators • Matrix multiplication is defined as intrinsic function • Modulus operator (%) works with integers <strong>and</strong> floats • Vector comparisons work on percomponent basis • Be careful with integer math – HLSL emulates integers if not natively supported, so rounding might produce different results
Flow Control • Branching if (expr) <strong>the</strong>n statement [else statement] • Loops do statement while (expr); while (expr) statement; for (expr1;expr2;expr3) statement • Loops are supported in all models – Unrolled if necessary
