| Projector Name | Parameters | Description | 
| chao | floatarray  anglelist:  int origin_x: int origin_y: int origin_z: float radius: transform transform:  | 
  Fast real space projection generation with Bi-Linear interpolation. | 
| fourier_gridding | floatarray  anglelist:  string angletype: float kb_K: float kb_alpha: int npad: float psi: float theta: transform transform:  | 
  Fourier-space projection using gridding. | 
| gauss_fft | int  mode:  int returnfft: transform transform:  | 
  Projections using a Gaussian kernel in Fourier space. Produces artifacts, not recommended. | 
| maxval | transform  transform: Transform object used for projection | 
  Real-space projection which computes the maximum value along each line projection rather than the sum | 
| pawel | floatarray  anglelist:  string angletype: int origin_x: int origin_y: int origin_z: float psi: int radius: float theta: transform transform:  | 
  Pawel Penczek's optimized real-space projection generation. Minor interpolation artifacts. | 
| standard | transform  transform: Transform object used for projection | 
  Simple real-space projection. Most accurate. |
