Where does sin(theta) go in estimators of The Rendering Equation?

Assume you want to estimate the following integral: $$I = \int_{\Omega} f d\mu$$ over the set $\Omega\subseteq \mathbb{R}^n$. Suppose you are given a bijective and continuously differentiable ...

Where does sin(theta) go in estimators of The Rendering Equation?

Your second equation is estimated with respect to solid angle $\Omega$, and the Jacobian of the transformation from spherical coordinates to solid angles is equal to $\sin\theta$. Since $\mathrm{d}\...
