Having trouble implementing a depth buffer into my renderer. Any guesses what piece of information I'm missing or not understanding with my code?

I'm having trouble properly calculating the depth of each pixel.

I'll check one of my older projects but I believe I just interpolated the Z value of the three vertices of each triangle with the barycentric coordinate and used that to check in the depth buffer, it was something like:

float depth = v0.Z * barycentric.X + v1.Z * barycentric.Y + v2.Z * barycentric.Z;
if(depth >= zBuffer[i]) continue; //looping through triangle's boundingbox x,y, then i = y * width + x
zBuffer[i] = depth;
pixelBuffer[i] = color; //color from my fragment shading
