/* useful unicode characters for Diderot

⊛
convolution, as in
field#2(3)[] F = bspln3 ⊛ image("img.nrrd");
LaTeX: \circledast is probably typical, but
\varoast (with \usepackage{stmaryrd}) is slightly more legible

×
cross product, as in
vec3 camU = normalize(camN × camUp);
LaTeX: \times

π
Pi, as in
real rad = degrees*π/360.0;
LaTeX: \pi

∇
Del, as in
vec3 grad = ∇F(pos);
LaTeX: \nabla

•
dot product, as in
real ld = norm • lightDir;
LaTeX: \bullet, although \cdot more typical for dot products

⊗
tensor product, as in
tensor[3,3] Proj = identity[3] - norm⊗norm
LaTeX: \otimes

∞
Infinity, as in
output real val = -∞;
LaTeX: \infty
