At present, when all 2.5-dimensional programs perform image rendering, a system d3d9.dll library file or an opengl32.dll library file is called certainly, and a unique d3d9.dll library file and a unique opengl32.dll library file are generated by rewriting the system d3d9.dll library file and the system opengl32.dll library file to replace the system d3d9.dll library file or the opengl32.dll library file, so that the third-party program operation can directly call the unique d3d9.dll library file and the unique opengl32.dll library file to display, thereby obtaining any program rendering stream, and displaying GPU codes of the unique d3d9.dll library file and the unique opengl32.dll library file along with a third-party stream, so that any third-party program rendering stream is processed and controlled in real time inside a GPU, and realizing 2.5-dimensional automatic three-dimensional image display.
Fig. 1 is a schematic flow chart of a method for displaying a 2.5-dimensional image in an auto-true stereoscopic manner according to an embodiment of the present disclosure.
As shown in fig. 1, the main flow of the method is described as follows (steps S101 to S105):
step S101, obtaining the eye distance of two eyes, the stereoscopic projection ratio and the visual range;
step S102, generating a projection offset matrix based on the binocular eye distance and the stereo projection ratio;
for step S102, calculating a monocular eye distance, and calculating a projection viewing cone offset based on the monocular eye distance and the saliency ratio; and acquiring an original unit matrix, and generating a projection offset matrix based on the original unit matrix and the projection cone offset.
In this embodiment, the eye distance is expressed by eyeLen, the stereoscopic projection ratio is expressed by sd, the visual distance is expressed by distance, the original unit Matrix is expressed by Matrix, the original unit Matrix is 4*4 Matrix composed of 16 floating point numbers, and the original unit Matrix is constructed as follows:
Matrix(1.0,0.0,0.0,0.0,
0.0,1.0,0.0,0.0,
0.0,0.0,1.0,0.0,
0.0,0.0,0.0,1.0)。
when calculating the projection view cone offset, the calculated view cone offset of a single eye is the eye distance of two eyes, so the eye distance of two eyes needs to be halved to calculate the eye distance of a single eye, the projection view cone offset is calculated according to the eye distance, i.e., eyeLen/(2.0 × sd), and the projection offset matrix offsetProjMatrix is generated by combining the original element matrix, and the projection offset matrix offsetProjMatrix is constructed as follows:
offsetProjMatrix = Matrix(1.0,0.0,0.0,0.0,
0.0,1.0,0.0,0.0,
eyeLen /(2.0*sd),0.0,1.0,0.0,
0.0,0.0,0.0,1.0)。
step S103, generating an observation offset matrix based on the binocular eye distance, the visual distance and the stereoscopic projection ratio;
for step S103, obtaining an offset parameter of an image space point; calculating an offset value of the image space point on the horizontal axis based on the offset parameter, the binocular eye distance, the stereoscopic prominence ratio, and the visual distance; and acquiring an original matrix, and generating an observation offset matrix based on the original matrix and the offset value.
In this embodiment, when calculating the offset value, first, a ratio of the visual distance to the stereoscopic projection ratio is calculated, the offset parameter, the binocular distance, and the ratio of the visual distance to the stereoscopic projection ratio are multiplied, the product is an offset value of an image space point on the horizontal axis, that is, an offset value of an image space point on the X axis, which is 0.5f × eyelen [ (/ sd) ], and an observation offset matrix offsetViewMatrix is generated by combining the original cell matrices, and the observation offset matrix offsetViewMatrix is configured as follows:
offsetViewMatrix = Matrix(1.0,0.0,0.0,0.0,
0.0,1.0,0.0,0.0,
0.0,0.0,1.0,0.0,
0.5f*eyeLen*(distance/sd),0.0,0.0,1.0)。
and step S104, acquiring a projection matrix, an observation matrix and an image space point position.
In this embodiment, the projection matrix ProjMatrix, the viewing matrix ViewMatrix, and the image space point location Postimion are obtained within the GPU in real-time from a unique d3d9.Dll library file and a unique opengl32.Dll library file.
And step S105, generating image space point true stereo imaging based on the projection offset matrix, the observation offset matrix, the projection matrix, the observation matrix and the image space point position.

In this embodiment, since true stereoscopic display requires that both the left and right eyes feel stereoscopic feeling, it is necessary to calculate display positions of the left and right eyes, i.e., both eyes, and generate stereoscopic imaging of an image space point from the display positions of both eyes at the time of calculation. It should be noted that each image space point needs to calculate the display positions of both eyes, and stereoscopic imaging of the entire image is generated based on the display positions of both eyes of all the image space points.
Further, the projection offset matrix and the observation offset matrix are negatively charged to generate a negative projection offset matrix and a negative observation offset matrix; calculating the product of the negative projection offset matrix and the projection matrix to generate a left-eye projection matrix; calculating the product of the negative observation offset matrix and the observation matrix to generate a left-eye observation matrix; and calculating the product of the left-eye projection matrix, the left-eye observation matrix and the position of the image space point to generate a left-eye display position.
In this embodiment, when calculating the left-eye display position, the image space viewpoint itself is used as the origin of coordinates, and the position of the left eye is located on the negative side of the X axis, so that it is necessary to generate a negative projection offset matrix-offset proj matrix and a negative observation offset matrix-offset ViewMatrix by negating the projection offset matrix and the observation offset matrix, respectively, multiply the projection offset matrix-offset proj matrix and the projection matrix by the projection matrix, and generate a left-eye projection matrix LProjMatrix _ new, i.e., LProjMatrix _ new = proj rix (-offsetproj matrix), the negative observation offset matrix-offsetViewMatrix and the observation matrix ViewMatrix are multiplied to generate a left-eye observation matrix LViewMatrix _ new, i.e., LViewMatrix _ new = (-offsetViewMatrix), the left-eye projection matrix LProjMatrix _ new, the left-eye observation matrix LViewMatrix _ new, and the image space point position Postion, to generate a left-eye display position, i.e., lpost _ new = LProjMatrix _ new @ LViewMatrix _ new.
Further, the projection offset matrix and the observation offset matrix are corrected to generate a forward projection offset matrix and a forward observation offset matrix; calculating the product of the orthographic projection offset matrix and the projection matrix to generate a right eye projection matrix; calculating the product of the forward observation offset matrix and the observation matrix to generate a right-eye observation matrix; and calculating the product of the right eye projection matrix, the right eye observation matrix and the position of the image space point to generate a right eye display position.
In this embodiment, it can be derived from the same calculation principle of the left eye, when calculating the display position of the right eye, the image space viewpoint itself is used as the origin of coordinates, and the position of the right eye is located on the positive side of the X axis, so that the projection offset matrix and the observation offset matrix need to be respectively corrected to generate a forward projection offset matrix + offsetproj matrix and a forward observation offset matrix + offsetViewMatrix, and the forward projection offset matrix + offsetproj matrix and the projection matrix are multiplied by the proj matrix to generate a right eye projection matrix RProjMatrix _ new, that is, RProjMatrix _ new = proj matrix (+ offsetproj matrix), and the forward observation offset matrix + offsetproj matrix and the observation matrix ViewMatrix are multiplied to generate a right eye observation matrix iewox _ new, that is, rviematrix _ new = proj matrix (+ view matrix), and rpnew _ matrix is multiplied by rpnetvistie matrix.
